Virtual Try-On Prompts: Nano Banana Guide
Master Nano Banana's complete virtual fashion studio. Generate outfit ideas, try them on your photos, and transform existing outfits into new styles.
Want to see if red is your color? Or how you'd look in a tuxedo? Nano Banana allows you to digitally "try on" clothes, preserving your identity while completely swapping the outfit.
Understanding Digital Dressing
The challenge with virtual try-on is Fit and Physics. A dress isn't just a texture painted on a body; it has weight, folds, and structure. You need to describe the fabric to get the form.
Example Starting Image
For the examples below, we'll use this look as our subject:
EVENING GOWN
Let's start with the foundation example from the Fashion & Styling overview. Here is the complete, fully detailed prompt to generate the "EVENING GOWN" try-on.
[Subject Image] Change outfit to a luxury evening gown. Preserve: - **Identity**: Face, hair, and body shape - **Pose**: Standing pose - **Background**: Keep original background Garment: - **Item**: Floor-length silk satin evening gown - **Color**: Ruby red - **Cut**: Halter neck with high slit on left leg - **Fit**: Form-fitting bodice, flowing skirt - **Fabric**: High-gloss satin (reflective) Details: - **Drape**: Natural fabric folds pooling on the floor - **Lighting**: Match the lighting of the original photo
Why This Works
The "High-Gloss Satin": Describing the finish ("high-gloss," "matte," "sheer") tells the AI how to render light reflections. Without this, the dress might look like flat colored paper.
The "Pooling on Floor": Details like "pooling," "billowing," or "cinched" describe the physics of the cloth. This anchors the subject to the ground and adds realism.
The "Form-Fitting" vs "Flowing": Contrasting fit descriptions helps the AI understand the silhouette. A dress can be tight in one place and loose in another.
Common Mistakes
Note:
Neckline Conflicts: If your original photo has a high collar or scarf, and you ask for a strapless dress, the AI has to invent the neck skin. This often looks fake. Try to match the coverage level or provide a photo with exposed neck/shoulders.
The Streetwear Look
Casual and oversized.
[Subject Image] Change outfit to streetwear. - **Top**: Oversized beige heavyweight hoodie - **Bottoms**: Black cargo pants with straps - **Shoes**: High-top chunky sneakers - **Accessories**: Black beanie hat - **Fit**: Baggy, relaxed, comfortable - **Fabric**: Thick cotton fleece
Key Detail: Using "heavyweight" and "baggy" defines the streetwear silhouette. Pairing oversized pieces with structured accessories (cargo straps, chunky sneakers) creates visual interest without fitting the body too tightly—essential for the relaxed streetwear aesthetic.
The Business Suit
Tailored and sharp.
[Subject Image] Change outfit to business formal. - **Suit**: Navy blue pinstripe double-breasted suit - **Shirt**: Crisp white dress shirt - **Fit**: Italian tailoring, slim fit - **Shoulders**: Structured padding - **Vibe**: Powerful, professional, executive
Key Detail: "Structured padding" and "slim fit" create sharp silhouettes that project authority. The pinstripe pattern and crisp white shirt add formality—without these specific details, the suit would look generic rather than executive.
The Swimwear (Fit Check)
Visualize beachwear.
[Subject Image] Change outfit to swimwear. - **Item**: One-piece swimsuit - **Pattern**: Tropical floral print - **Cut**: Vintage high-leg cut - **Fabric**: Lycra/Spandex (matte finish) - **Context**: Ensure skin tone matches face perfectly
Key Detail: "Matte finish" and "Lycra/Spandex" tell the AI how the swimsuit clings to the body without glossy reflections. The "vintage high-leg cut" is a specific silhouette detail—without it, you might get modern cuts that don't match the intended aesthetic.
The Historical Costume
Travel through time.
[Subject Image] Change outfit to Victorian era costume. - **Item**: 1890s ballgown - **Details**: Lace collar, corset waist, bustle skirt - **Fabric**: Velvet and lace - **Props**: Holding a lace fan - **Vibe**: Period drama, elegant
Key Detail: Naming the specific era ("1890s") and architectural details ("bustle skirt," "corset waist") anchors the design to a real historical period. Without these, you might get a vague "fancy dress" rather than an authentic Victorian silhouette. Props like the "lace fan" add period-appropriate context.
Example Starting Image
Now let's try a different person. Here's our new subject for the wardrobe swaps below:
GALA READY
Let's start with the foundation example from the Fashion & Styling overview. Here is the complete, fully detailed prompt to generate the "GALA READY" transformation.
[Subject Image] Transform casual clothes into formal evening wear. Preserve: - Facial features and expression exactly - Hair style and grooming - Body posture and pose - Background environment - Lighting direction and quality Transform: - **Outfit (Male)**: Classic black tuxedo with satin peak lapels - **Shirt**: Crisp white formal dress shirt with pleated front - **Accessories**: Black bow tie (not pre-tied), pocket square, cufflinks - **Fit**: Tailored, sharp, proper proportions **Outfit (Female)**: Elegant floor-length evening gown - **Style**: Off-shoulder or halter design in deep jewel tone (emerald, sapphire, burgundy) - **Material**: Flowing silk or satin with subtle sheen - **Details**: Tasteful jewelry (drop earrings, bracelet) Context Adjustment: - **Background**: Red carpet event or upscale gala venue - **Lighting**: Professional flash photography style - **Overall Vibe**: Black-tie formal, sophisticated, high-end event
Key Detail: The "Preserve" section is crucial here. By explicitly telling the AI to keep facial features, pose, and background unchanged, you're transforming only the clothes while maintaining the person's identity and the photo's authenticity.
The Winter Layering Look
Practical and stylish.
[Subject Image] Style a cozy winter outfit. - **Base**: Black slim-fit jeans or chinos - **Top**: Charcoal wool crew-neck sweater - **Outerwear**: Navy wool peacoat - **Accessories**: Gray knit beanie, wool scarf, leather gloves - **Shoes**: Brown leather boots or Chelsea boots - **Vibe**: Casual, warm, rugged
Key Detail: Layering works because you specify each piece separately with distinct materials (wool sweater, wool coat, leather boots). This tells the AI how textures stack and interact, creating visual depth and realistic fabric weight.
The Business Casual Upgrade
From weekend wear to office appropriate.
[Subject Image] Transform casual outfit into business casual attire. - **Outfit**: Navy blazer over light blue oxford button-down - **Bottoms**: Khaki chinos (not jeans) - **Shoes**: Brown leather loafers or dress shoes - **Accessories**: Leather belt, simple watch - **Fit**: Clean, pressed, professional but not formal - **Vibe**: Office-ready, approachable professional
Key Detail: The navy blazer is the transformation anchor—it signals professionalism instantly. Pairing it with a light blue oxford (not white, which reads too formal) and khaki chinos (not black, which reads too casual) hits the business casual sweet spot. The "not jeans" and "not formal" balance tells the AI you want something between weekend and boardroom.
The Athleisure Swap
From formal to activewear chic.
[Subject Image] Transform formal clothes into stylish athleisure. - **Top**: High-quality tech fabric hoodie or quarter-zip pullover - **Bottoms**: Fitted joggers or performance leggings - **Shoes**: Clean white sneakers (minimalist style) - **Accessories**: Athletic watch or fitness tracker - **Brands**: Lululemon / Athleta / Nike aesthetic - **Vibe**: Gym-to-street, wellness lifestyle
Key Detail: The term "tech fabric" is crucial—it tells the AI to render moisture-wicking, modern sportswear rather than plain cotton. Pairing this with brand references (Lululemon, Athleta, Nike) grounds the aesthetic in recognizable luxury activewear rather than basic gym clothes. The "clean white sneakers" and "minimalist style" keep the look upscale and intentional.
