How outfit swapping works
Inpainting treats the masked garment as a hole and fills it with a new one, using the unmasked body and scene as constraints. Shoulders, posture, and arm positions anchor how the fabric drapes; the scene's light dictates where highlights and shadow folds fall. That's why swapped clothes sit naturally on the body instead of looking pasted on.
Because only the masked region regenerates, identity survives untouched — the model never redraws the face. That's the practical difference from whole-image restyle tools, which repaint the person along with the clothes.
Describe garments like a costume designer
Generic prompts get generic clothes. Name the garment type and construction: 'double-breasted navy blazer, peak lapels' beats 'nice jacket'. Add fabric, because fabric drives how the model renders drape and sheen — wool falls differently than silk, denim creases differently than jersey.
Fit words do heavy lifting too: 'oversized', 'tailored', 'cropped', 'high-waisted' each change the silhouette. For color, use real clothing vocabulary — 'ivory', 'charcoal', 'camel' — and mention finish when it matters: 'matte black leather jacket' and 'glossy black leather jacket' are two different garments.
Mask for the outfit you want, not the one you have
The mask defines where new clothing is allowed to exist, so size it for the target garment. Swapping a t-shirt for a winter coat means masking beyond the t-shirt's outline — the coat needs room for its collar, bulk, and length. Masking only the current garment forces the new one into the old silhouette.
Include the edge zones where fabric meets skin or background: collars, cuffs, hems. A little generosity at those boundaries lets the model blend transitions cleanly instead of inheriting the old garment's edges.
What it's for — and consent
The productive uses are look development and content efficiency: testing a lookbook direction before a shoot, generating outfit variations from one good photo for a style feed, putting a merch design's colorways on the same model shot, or fixing the profile photo where the face is great and the hoodie isn't.
Edit photos of yourself, or of people who've agreed to the edit. Using this on someone's photo without consent — or to depict someone in a way they'd object to — is a hard no under our acceptable-use policy.
