# Try-on guide

## Consent and safety

- Own photo or written consent, every time. No consent, no image.
- Refuse celebrities, public figures, strangers, and anyone who looks under 18.
- Keep outputs clothed and ordinary. Do not alter body shape, skin, age or face. Do not add jewellery, tattoos or accessories that were not in the photos.

## Choosing the photos

- Person: front-facing, even light, plain background, torso and arms visible. The photo's crop and pose become the result's crop and pose.
- Garment: flat-lay or hanger shot with the whole garment, good light, no folds hiding the collar or buttons. A photo of the garment on another person also works; say "ignore the person wearing it".
- Different light in the two photos is fine; the model relights the garment to match the person's photo.

## Keeping the garment true

Write the garment's identity into the prompt, not just "this shirt":

- Colour in plain words ("oatmeal cream", "olive", "navy"), never brand colour names.
- Fabric and finish ("slubby matte linen", "glossy nylon", "heavy knit"). Add "not shiny, not satin" for matte fabrics.
- Construction: collar type, placket, number and colour of buttons, cuffs, pockets, hem, print or pattern placement.
- How it is worn: buttoned or open, sleeves down or rolled, tucked or untucked.

## Keeping the person true

- Say "keep her/him exactly: face, hair, skin, expression, pose, background and light".
- Replace only the clothing in the garment area. Name the garment being replaced ("the white t-shirt").
- Add "no necklace, no added jewellery" when the original has none; models sometimes invent one.

## Model choice

- Dedicated try-on models are fast and cheap but can turn linen, cotton or knit into shiny satin and invent wrinkles. Test one only for plain, smooth garments.
- The default is a multi-image edit model given both photos and a detailed prompt. It kept fabric weave, buttons and identity in testing.

## Garment types

Worn fabric shows fewer wrinkles than a flat-lay. Tell the model to drape it naturally rather than copy the flat-lay creases.

| Garment | What to say and check |
|---|---|
| Tops, shirts, tees | Name what is replaced ("the white t-shirt"). State tucked or untucked and buttoned or open. Check collar, placket and button count. |
| Outerwear over a top | Say "worn open over the existing top" or "closed". Keep the top under it unchanged. Check the lining shows at the collar. |
| Dresses | The person photo must show the area the dress covers. Replace the whole outfit named in the prompt. Check hem length and waistline. |
| Trousers, skirts | Use a full-body or at least hip-to-knee person photo. Say "replace the trousers only". Check rise, break at the ankle, and that shoes are unchanged. |
| Long vs short sleeves, exposed skin | Going from short to long sleeves covers skin; long to short must invent arms. Prefer a person photo with similar sleeve length, or say "keep her natural forearms and skin tone". |
| Tucked vs untucked | State it. A tuck needs the waistband area visible. |
| Longer garments (coats, long dresses) | Frame the person head to knee or longer; a waist-up photo cannot show the hem. Ask for a full-length photo. |

## Quality setting

The shipped defaults are 1536 × 2048 at quality high (about $0.25 per image) and are what made the preview. Medium quality (960 × 1280, about $0.10) is fine for quick drafts but gives softer fabric detail.

## Failure fixes

| Problem | Fix |
|---|---|
| Fabric looks shiny or plastic | Name the fabric and finish; add "matte, not satin"; mention the weave |
| Buttons wrong number or colour | Count them in the prompt and name their colour |
| Face looks different | Repeat "keep her exactly"; use a higher quality setting |
| Collar or cuffs changed | Describe the collar and cuffs in words |
| Garment too big or small | State the fit: "relaxed", "slim", "oversized" |
| Extra jewellery or accessories | Add "no added jewellery or accessories" |
