New Release! AI Clothes Try-On API v.4

Sep 16, 2026 · 3 minutes read
AI Clothes Try-On API V4: virtual outerwear jacket and vest try-on

Picture a shopper browsing your fashion site. She tries on the sweater, loves it, adds it to cart. Then she scrolls to the matching jacket and taps try-on, and nothing happens.

Outerwear has always been the blind spot in virtual fitting rooms. It is also the category shoppers ask about most before they check out: does this coat actually work over that outfit? AI Clothes Try-On API V4 closes that gap.

What's new in V4

V4 keeps every core function of AI Clothes Virtual Try-On V3 intact. Same accuracy, same server cost, same 2.0 API structure. The one addition is the one shoppers kept asking for: outer, a new garment category built specifically for jackets, coats, and vests.

Before V4, layering pieces had to be squeezed into the same upper body or full body categories as shirts and dresses, which is not what an outer layer actually looks like on a person. Now it gets its own dedicated pipeline.

How outerwear try-on works

Outerwear try-on runs through the same three endpoints as the rest of the Clothes API, just with one new value in the garment_category parameter: outer.

How outerwear try-on works

Send a user photo and a reference photo of the jacket or vest, set garment_category to outer, and the API renders the outer layer onto the person realistically, on top of whatever they're already wearing. No separate integration, no new SDK, no extra setup.

The full parameter set stays familiar if you've integrated V3:

  • User photo (URL or File ID): a front-facing photo showing the body part the shopper wants to try the garment on.
  • Reference photo (URL or File ID): the garment photo, either a clean product shot or one with a model, front-facing.
  • garment_category: full body, lower body, upper body, shoes, auto, or the new outer.
  • change_shoes (optional, default true): controls whether shoes swap too, when the category is full body or lower body.

The output is exactly what you'd expect: a single result photo URL with the try-on rendered.

Getting started with V4

V4 ships on Perfect Corp's simplified 2.0 API architecture only. If your integration is still on the legacy API, this is a good moment to move over.

Three endpoints power the whole flow:

  • POST Create a new file (V4)
  • POST Run AI Clothes V4 task
  • GET Check AI Clothes V4 task status

Pricing hasn't changed: outerwear try-on costs the same 2 units per image as every other V3 render, since it runs on the same AI model and server infrastructure. No premium tier, no separate quota to plan around.

FAQ

Do I need to change my existing V3 integration to use outerwear try-on?
No new endpoints or SDK version. Just pass outer as the garment_category value on your existing V4 request.

Can outerwear be combined with a full outfit change in one request?
Each request handles one garment category at a time. To show a full layered look, run the base outfit through its category first, then layer the jacket or vest with a second outer request on the result.

Does outerwear try-on cost more than a standard try-on?
No. It's priced the same as every other V4 category: 2 units per image.

Does V4 support multiple people in one photo?
No, same as V2 and V3, V4 supports single-person photos only.
