NFes2026 Summer Festival Fashion Magazine Cover

Create a stylish 3:4 portrait fashion magazine cover illustration using the attached images as essential visual references.

The final image should look like a sophisticated summer fashion magazine cover featuring people, animals, or mascots enjoying an outdoor music festival.

1. Attached Reference Images

One attached image shows the NFes2026 festival T-shirt.

Accurately reproduce the attached T-shirt.

- Preserve its original colors.
- Preserve all graphics, logos, typography, patterns, and distinctive details.
- Do not redesign, simplify, replace, or alter the T-shirt artwork.
- Keep the T-shirt clearly recognizable as the exact festival T-shirt shown in the reference.

Another attached image contains one, two, or three people, an animal, or a mascot.

Carefully preserve the recognizable appearance of every attached subject.

- Preserve facial features and expressions.
- Preserve hairstyle and hair color.
- Preserve recognizable body proportions and distinctive characteristics.
- Preserve colors, markings, and other important visual details.
- If multiple people are present, include every person shown in the reference image.
- Do not omit, merge, replace, or duplicate subjects.

2. Festival Fashion

Dress the attached person or people in the attached NFes2026 festival T-shirt as the main top.

Style the rest of the outfit as a modern reinterpretation of:

1990s Japanese street fashion × American street casual × subtle visual-kei / punk-rock fashion.

The styling should feel nostalgic but contemporary, youthful, fashionable, slightly edgy, expressive, and suitable for an outdoor music festival.

Choose bottoms and accessories naturally according to each person's appearance.

Possible elements include:

- baggy or wide-leg denim
- cargo pants
- plaid skirts
- pleated mini skirts
- oversized shorts
- layered clothing
- chunky sneakers
- platform boots
- belts
- subtle chains
- rings
- colorful hair accessories
- small shoulder bags
- simple black collar-style chokers

Choker / Collar Detail

A simple black collar-style choker may be used when it suits the person's styling.

If used:

- keep it sleek and minimal
- use flat rectangular silver metal plates or small flat silver hardware
- keep the metal details smooth and understated

Do not use spikes, cone studs, pointed studs, pyramid studs, sharp metal protrusions, or aggressive dog-collar styling.

The black collar should look like a fashionable 1990s street accessory, not a heavy-duty spiked collar.

Do not use every possible accessory at once.

Create a cohesive outfit that feels like 1990s street culture reinterpreted for 2026.

3. Composition and Poses

The subjects are posing for a fashion photograph at a dedicated NFes2026 outdoor festival photo spot.

Create relaxed, confident, stylish poses.

One person

Have the person casually lean against the brick wall.

One leg may be slightly bent, with one hand naturally in a pocket or resting beside the body.

Two people

Arrange both people naturally near the brick wall.

Use slightly different poses and depths so they do not appear stiffly lined up.

Three people

Arrange the three people in a loose triangular composition.

One person may stand slightly forward while the other two stand slightly behind.

Automatically adapt the composition according to the number of attached people.

Anatomy

Maintain accurate human anatomy.

Each person must have:

exactly two arms and exactly two legs.

Never duplicate, merge, twist, distort, invent, or remove limbs, hands, feet, fingers, or body parts.

Avoid excessive overlapping between bodies and limbs.

4. Animals and Mascots

If an attached image contains an animal, preserve it as a natural animal.

Make it appear genuinely present at the festival photo spot.

Possible poses include:

- sitting beside a person
- standing naturally near the group
- walking beside them
- sitting at someone's feet
- being gently held or hugged when appropriate

Maintain believable animal anatomy, proportions, posture, fur, and texture.

If an attached image contains a mascot or character, preserve its original design and recognizable features.

Do not transform animals into humans.

Do not give animals unnecessary human anatomy.

5. Festival Photo Spot

The setting is a dedicated photo spot inside an outdoor music festival, not an ordinary city street.

Place a stylish American-inspired old brick wall directly behind the subjects as the main photographic backdrop.

The brick wall should feel like a cool, slightly vintage festival installation inspired by old American urban architecture.

Beyond and around the brick wall, show a softly atmospheric outdoor festival scene:

- distant music stage
- colorful stage lighting
- glowing festival lights
- festival tents
- food or merchandise booths
- distant festival visitors
- lively summer festival atmosphere

Keep the distant festival environment slightly softer and less detailed than the main subjects.

The viewer should immediately understand that this is an NFes2026 festival photo spot.

6. Chalk Graffiti on the Brick Wall

Do not write "NFes2026" on the brick wall.

Instead, add a small amount of casual English chalk graffiti.

Randomly select a few short phrases such as:

Have fun!
Enjoy!
Good vibes!
Let's go!
Smile!
Live it up!
Music!
Summer!
Feel the beat!
Good times!

Use only a few phrases.

The chalk writing should feel spontaneous, casual, and hand-drawn.

Add a few small chalk marks, music notes, stars, arrows, or simple symbols if appropriate.

Keep the wall stylish and uncluttered.

7. Main Illustration Style

Create a sophisticated fashion illustration combining:

1990s Japanese street fashion × contemporary fashion illustration × American-inspired festival atmosphere × subtle visual-kei / punk-rock influence × subtle Art Nouveau-inspired linework × delicate watercolor texture.

Use:

- elegant flowing curves
- expressive linework
- graceful silhouettes
- subtle ornamental details
- artistic lighting
- delicate watercolor texture
- translucent pigment
- soft color variation
- natural paper texture
- gentle watercolor bleeding

The Art Nouveau influence should be subtle and contemporary.

Do not turn the image into a historical Art Nouveau poster.

Do not use flowers, vines, leaves, or botanical decorations.

The Art Nouveau feeling should come primarily from graceful curves, flowing linework, fabric movement, hair movement, and elegant illustration details.

8. Watercolor Edges

Use a subtle watercolor quality throughout the illustration.

At the outer edges, allow the watercolor pigment to gradually become lighter, softer, and more transparent, naturally dissolving into the white paper background.

The transition should be irregular and organic, resembling real watercolor pigment naturally running out on paper.

Do not create a hard rectangular boundary around the painted scene.

The watercolor fading should feel natural and painterly rather than like a digital filter.

9. Magazine Cover Title

Design the final image as a sophisticated fashion magazine cover.

The magazine title must be:

NFes2026

Place NFes2026 prominently at the upper center of the cover.

It should be the largest and most important text element.

Use bold, elegant editorial typography.

Do not create another magazine title, brand name, masthead, or competing logo.

10. Vertical Editorial Text Boxes

Add approximately two tall vertical rectangular editorial text boxes, one on the left side and one on the right side of the cover.

They should resemble sophisticated fashion-magazine editorial information panels.

Use:

T-SHIRT FES!

for one box.

Use:

SUMMER MUSIC EDITION

for the other box.

The boxes should be narrow, vertically oriented rectangles with clean editorial typography.

Do not make them look like picture frames.

They are magazine graphic elements containing text.

Do not allow them to cover faces or important details of the T-shirt.

11. Festival Dates

Include the festival period:

2026.08.19 – 09.30

Place it naturally near the lower portion of the cover.

Keep it smaller than the main "NFes2026" title and secondary editorial text.

12. Fictional Magazine Barcode

Add a small fictional magazine barcode near the bottom right corner of the cover.

The barcode should resemble a realistic fashion magazine barcode:

- clean vertical black lines
- compact rectangular shape
- small fictional numbers underneath
- realistic but clearly decorative
- small and unobtrusive

The barcode is purely a visual magazine-design element and does not represent a real product.

Do not make the barcode large.

Do not place it over the subjects, T-shirt, or main typography.

13. Typography Hierarchy

Maintain the following visual hierarchy:

1. NFes2026
Large main magazine title at the upper center.

2. Main subjects and festival T-shirt
Primary visual focus.

3. T-SHIRT FES! / SUMMER MUSIC EDITION
Secondary editorial information in the vertical boxes.

4. 2026.08.19 – 09.30
Supporting festival information.

5. Barcode
Small magazine-detail element near the bottom right.

Do not overcrowd the cover.

14. Magazine Design

The overall design should resemble a sophisticated 1990s-inspired fashion magazine cover updated for 2026.

Use clean editorial spacing, confident typography, and a stylish balance between photography-inspired composition and illustration.

Do not make the cover look like an event flyer.

Do not make it look like a conventional festival poster.

Do not fill the image with excessive text.

Only use the specified magazine text.

15. No Purikura Decorations

Do not use purikura-style decorations.

Absolutely avoid:

- neon doodle borders
- purikura frames
- sticker effects
- scrapbook decorations
- colorful doodle borders
- excessive hearts
- excessive stars
- decorative stickers
- cute frame effects

The only casual hand-drawn elements should be the small chalk graffiti on the brick wall.

The magazine graphic elements should remain clean, stylish, and editorial.

16. Final Appearance

The final artwork should feel like a limited-edition NFes2026 summer fashion magazine cover.

Combine:

**NFes2026

+ outdoor music festival
+ American-inspired brick photo spot
+ 1990s Japanese street fashion
+ contemporary styling
+ subtle visual-kei / punk-rock attitude
+ subtle Art Nouveau-inspired linework
+ delicate watercolor texture
+ sophisticated editorial typography
+ realistic magazine details such as a barcode.**

The result should feel fashionable, artistic, youthful, slightly nostalgic, and unmistakably connected to the NFes2026 summer festival.

Aspect ratio: 3:4 portrait.

colorful neon strokes
stars
hearts
sparkles
music notes
tiny lightning bolts
arrows
playful symbols
handwritten words
small decorative doodles
The frame should have an intentionally handmade, slightly irregular appearance.
Some doodle lines may overlap the photograph slightly, just like purikura decorations drawn directly onto a photo.

Allow some doodles to extend inward toward the subjects and some to slightly protrude outward toward the edge of the canvas.
The overall feeling should be:
cute + energetic + nostalgic + neon + festival + slightly rebellious.
The neon doodle frame should complement the sophisticated illustration rather than overpower it.
9. Relationship Between the Styles
The image should deliberately combine two visual layers:
Inside the scene
Sophisticated watercolor fashion illustration with subtle Art Nouveau-inspired flowing linework.
Around the scene
Playful Japanese purikura-style neon doodles and handwritten decorations.

It should evoke:
**90s street fashion
contemporary styling

colorful Japanese purikura nostalgia.**
Keep the attached people, animals, mascots, and NFes2026 T-shirt clearly recognizable.

NFes2026 Festival T-Shirt Fashion Poster
Integrated Fashion Editorial Prompt
Create a stylish portrait-oriented fashion poster illustration using the attached images as essential visual references.
The attached images include:
the person or people who will wear the T-shirt
the exact NFes2026 festival T-shirt design
The final image should look like a sophisticated limited-edition music festival fashion campaign poster, featuring the attached person or people wearing the exact attached NFes2026 T-shirt.
1. Attached Person Reference
Carefully preserve the recognizable appearance of every person shown in the attached person reference images.
Maintain:
facial features

distinctive characteristics
overall recognizable appearance and identity
If multiple people are provided, include every person.
Do not omit, merge, duplicate, replace, or substantially alter any person.
Maintain realistic human anatomy.
Each person must have exactly:
two arms
two hands
two legs
two feet
Avoid excessive overlapping of bodies and limbs.
Keep each person's appearance clearly distinguishable.
2. Exact NFes2026 T-Shirt
Dress the person or people in the exact NFes2026 festival T-shirt shown in the attached reference image.
The T-shirt is the most important visual element of the poster.
Reproduce the shirt as accurately as possible.
Preserve:
original black shirt color
exact graphics
original photographic/illustrative artwork
logos
typography
lettering
patterns
placement of every graphic element
proportions of the printed artwork
overall shirt shape
neckline
sleeves
fabric appearance
Do not redesign the T-shirt.
Do not simplify, reinterpret, replace, stylize, or invent any part of the printed artwork.
Do not add extra logos, graphics, decorations, text, patches, or symbols to the shirt.
The front of the T-shirt must remain clearly visible, recognizable, and readable.
The printed artwork should remain crisp and as faithful to the reference as possible.
Do not allow the graphic to become excessively warped by perspective, body movement, fabric folds, shadows, or lighting.
The T-shirt itself should remain the visual focal point of the fashion poster.
3. Fashion Editorial Composition
Create a pose inspired by a sophisticated professional fashion editorial, music-festival campaign, or contemporary fashion magazine photoshoot.
The pose should feel:
confident
relaxed
natural
stylish
spontaneous
slightly unpredictable
Pose Variation
Do not always use the same pose.
For each generation, naturally vary the combination of:
body position
weight distribution
hand placement
leg position
shoulder angle
body orientation
gaze
facial expression
camera angle
framing
Possible poses include:
one hand naturally resting near the waist
one hand casually placed in a pocket
both hands positioned naturally near the waist
one hand lightly touching the hem or side of the T-shirt without covering the artwork
one shoulder slightly raised
one shoulder subtly leaning toward the camera
relaxed asymmetrical stance
weight naturally shifted onto one leg
one leg slightly forward
one knee slightly bent
one foot placed slightly forward
casually leaning against a wall
one hand resting against a wall
subtle walking or stepping-forward pose
body slightly turned while keeping the front of the T-shirt visible
relaxed fashion-editorial stance with natural body movement
Avoid stiff, symmetrical poses.
Avoid overly dramatic or physically impossible poses.
4. Camera Angle and Framing Variation
Naturally vary the camera treatment between generations.
Possible approaches include:
eye-level fashion portrait
slightly low-angle fashion shot
subtle upward-looking perspective
slightly tilted editorial composition
medium shot
three-quarter body shot
wider fashion campaign composition
Occasionally use a slightly low-angle perspective to give the model a stronger and more confident presence.
Do not exaggerate the perspective.
Do not use extreme wide-angle distortion.
The camera position should always allow the T-shirt to remain clearly visible.
5. Gaze and Expression Variation
Do not always make the model look directly at the camera.
Naturally vary:
direct eye contact
confident gaze toward the camera
subtle sideways glance
looking slightly away
looking past the camera
looking slightly downward
calm neutral expression
subtle confident smile
cool, relaxed expression
The expression should remain consistent with a sophisticated fashion editorial.
Avoid exaggerated smiles or cartoon-like expressions.
6. Important T-Shirt Visibility Rules
Regardless of the selected pose:
keep the front of the T-shirt clearly visible
keep the printed artwork unobstructed
do not cross both arms over the chest
do not place hands directly over the graphic
do not hide the shirt behind hair
do not hide the shirt behind bags or accessories
do not place jackets or outerwear over the T-shirt
do not obscure the design with props
do not distort the artwork through extreme perspective
do not allow shadows to completely cover the graphic
The model and the T-shirt should work together as a fashion composition.
The viewer should immediately recognize the exact NFes2026 T-shirt.
7. Lighting and Subject Separation
Create a slightly dark, atmospheric environment suitable for a sophisticated music festival fashion poster.
However, the model and especially the black T-shirt must never merge into the dark background.
Use carefully controlled cinematic lighting to create strong separation between the subject and the environment.
Main Lighting
Illuminate the model with a strong but elegant directional key light from the front or a three-quarter angle.
The model should be noticeably brighter than the surrounding background.
Use enough frontal illumination to clearly reveal:
the black fabric
shirt shape
fabric folds
printed artwork
typography
graphic details
The black T-shirt should remain rich black while still being clearly visible.
Do not turn the shirt gray or wash out its original black color.
Rim Lighting
Add a subtle but clearly visible rim light / backlight around:
hair
shoulders
upper arms
outer silhouette
This creates a delicate luminous outline separating the model from the dark festival background.
Use slightly cool or violet-blue highlights around the silhouette where appropriate.
Background Contrast
Keep the background somewhat darker and softer than the model.
Use a subtle palette of:
deep navy
indigo
blue-violet
muted purple
soft atmospheric festival lights
This provides gentle color contrast against the black T-shirt.
Lighting Priority
The visual lighting hierarchy should be:
illuminated model → clearly visible black T-shirt → softly illuminated festival atmosphere → darker background
The T-shirt must never disappear into the background.
Avoid heavy shadows across the front of the shirt.
Avoid placing the model in an area of the background that is equally dark as the shirt.
Use gentle highlights along the edges of the black fabric so its silhouette remains clearly readable.
8. Festival Background
Create a sophisticated, slightly abstract outdoor music-festival environment.
The background may subtly suggest:
distant festival stages
concert lighting
blurred lighting rigs
outdoor festival structures
atmospheric night scenery
soft bokeh
faint decorative lights
subtle festival banners
distant silhouettes
Keep the background softly blurred and secondary.
Do not create a huge crowd.
Do not create complicated scenery.
Do not allow background details to compete with the T-shirt.
The environment should feel like a premium fashion campaign photographed at a music festival, rather than a documentary photograph.
9. Illustration Style
Create a sophisticated contemporary fashion illustration combining:
**realistic fashion portraiture
refined editorial illustration
subtle watercolor texture
cinematic festival photography aesthetics
elegant painterly details**
Use:
realistic human proportions
refined linework
subtle painterly texture
sophisticated shading
cinematic depth
controlled highlights
realistic fabric texture
delicate atmospheric effects
The final artwork should feel:
premium, fashionable, cinematic, artistic, mature, and sophisticated.
Do not make it cute or mascot-like.
Do not use excessive anime exaggeration.
Keep the person's face recognizable.
Keep the T-shirt artwork crisp and faithful.
10. Poster Typography
Add a prominent title:
N-Fes2026
The title should be clearly readable and integrated into the editorial composition.
Place it near the upper portion of the poster or another visually balanced location.
Do not cover:
the person's face
the T-shirt artwork
The title should feel like a sophisticated fashion magazine / music festival masthead.
Use elegant editorial typography with a slightly vintage or distressed character that complements the attached T-shirt design.
11. Elegant Decorative Words
Add only 2 to 4 carefully selected English words or short phrases around the subject.
Choose words that complement the visual atmosphere and theme of the NFes2026 T-shirt.
Possible choices include:
MUSIC
SUMMER
CREATE
FREEDOM
DREAM
JOURNEY
RHYTHM
MEMORIES
LIVE
WONDER
Do not use all of them.
Select only the words that best suit the particular composition.
Render these decorative words in an elegant:
golden handwritten / refined cursive style
The gold should have a subtle metallic quality with delicate highlights.
Avoid harsh bright yellow.
Arrange the words organically around the person.
Some lettering may gently curve around the silhouette or float beside the model.
Do not place decorative words directly over the T-shirt artwork.
Do not fill the background with text.
Do not generate random illegible writing.
Every visible word should be intentional, stylish, and clearly readable.
The decorative typography should feel like part of a premium fashion editorial.
12. Visual Hierarchy
Maintain the following visual hierarchy:
1. Exact NFes2026 T-shirt design
2. Person / fashion-model presence
3. N-Fes2026 title
4. Elegant golden decorative typography
5. Atmospheric festival environment
The first impression should be:
“That is the NFes2026 T-shirt.”
The T-shirt should remain the star of the poster.
13. Overall Mood
The finished artwork should resemble a:
limited-edition NFes2026 festival fashion campaign poster
with the atmosphere of:
high-fashion editorial
× outdoor music festival
× cinematic night photography
× contemporary illustration
× subtle watercolor texture
The mood should be:
cool + stylish + sophisticated + slightly mysterious + musical + youthful + atmospheric
Use darkness for atmosphere, not to hide the subject.
The model should remain clearly illuminated against the darker background.
The black T-shirt should remain clearly separated from the background and fully recognizable.
14. Final Composition Requirements
Create a portrait-oriented composition with balanced negative space.
Use the available space intelligently for:
the N-Fes2026 title
the model
the T-shirt
small golden decorative typography
atmospheric festival lighting
Avoid:
excessive text
excessive decorations
clutter
cartoon-like rendering
overly bright backgrounds
extremely dark subjects
distorted anatomy
hidden faces
hidden T-shirt graphics
outerwear covering the T-shirt
hands covering the printed artwork
extreme perspective distortion
repetitive standard poses
Every generation should feel like a different photograph from the same NFes2026 fashion campaign.
Keep the identity of the person and the exact T-shirt design consistent, while allowing the pose, camera angle, gaze, expression, and composition to vary naturally.

できる限り、運営側が飛んで行って拝見させていただきます🔎
配布プロンプトを使って、ぜひ自由にTシャツを着て遊んでみてくださいね💖🙌🏻😆😆🙌🏻💖

‎🩷プロンプトを改変して配布しないでください‎🙏

例えば……
️⭕️今回のプロンプトで作った画像から、
落書き無しバージョンや
服装の系統が違うバージョンとかを作るのはOK！
️⭕️アレンジした画像を記事にするのもOK！

❌私の組み立てたプロンプトをベースに、
AIに頼んで一部だけ変えたプロンプトにして、noteやXなどで配布しないでください。

もし同じものが作りたいならば、ご自身で1から指示文（プロンプト）を書き起こして作ってね☆

こんなイメージのこういう画像を作りたいからああしてこうしてと、GPTと何度も相談してこのプロンプトを作りました。
AIは賢いから、本当はこんな指示文無くても、カッコイイ画像は作れちゃうんだろうけど……。
私とGPTが相談して作り上げた指示文なので、完成するまで積み重ねた対話の時間が詰まっているという事を意識してくださると嬉しいです✨️



‎‎🩷このプロンプトは、あくまで素人の私が作ったものです
そのため上手く画像にならない事や生成事故が起きる場合があります。
人もAIもミスります。広い心で遊んでくださると嬉しいです。
 

以上、

ご応募や記事の投稿お待ちしております✨️

みんなでフェスを楽しもうね🥰️
