# Clothing AI Try-On

AI try-on for clothing. Merchants start at [See a garment](../clothing/see-on-person.md). A size estimate is a second recipe, [Recommend a clothing size](../clothing/recommend-size.md). Shoe size does not use this API.

## What It Does

Shoppers can see how clothing looks on them (or a model) using generative AI. The system creates a **digital twin** of the person and applies selected garments virtually.

## Key Features
- **Digital twin** — AI-generated representation of the shopper
- **Virtual fitting** — see how clothes look on the digital twin
- **Estimated size fitting** — on [tryon.wearfits.com](https://tryon.wearfits.com), a twin created from body measurements or a clothing size can be compared with the product's body size chart. The result is a recommended size and a fit, loose, or tight reading. It does not show a 3D heatmap and it does not return the shopper's measurements.
- **Embeddable** — clients can embed the try-on in an iframe or modal window
## How to Use

| Method | Description |
|--------|-------------|
| **Frontend app** | [tryon.wearfits.com](https://tryon.wearfits.com) — example implementation |
| **Iframe / modal** | Embed tryon.wearfits.com in your website |
| **API** | Direct API calls for custom implementations — see [API Reference](api-reference.md) |

## API Endpoints
| Endpoint | Description |
|----------|-------------|
| `POST /api/v1/digital-twin` | Generate a digital twin image |
| `POST /api/v1/virtual-fitting` | Apply clothing to digital twin |
| `POST /api/v1/size-fitting` | Synchronously compare an eligible measurement or clothing-size digital twin with merchant body-range size charts and return estimated fit results |
## Domain

- **API**: [api.wearfits.com](https://api.wearfits.com)
- **Frontend**: [tryon.wearfits.com](https://tryon.wearfits.com)

## How It Works

```mermaid

    participant User
    participant App as tryon.wearfits.com
    participant API as api.wearfits.com

    User->>App: Capture selfie and enter measurements
    App->>API: POST /api/v1/digital-twin
    API-->>App: Digital twin ready
    User->>App: Select garments
    App->>API: POST /api/v1/virtual-fitting
    API-->>App: Fitting result
    App->>User: Display try-on image
    User->>App: Ask how a size fits
    App->>API: POST /api/v1/size-fitting
    API-->>App: Recommended size and fit
    App->>User: Show fit, loose, or tight
```

Size fitting runs only for a Size Mode twin (measurements or clothing size). A photo-mode twin does not get a size estimate.

## Digital Twin Modes
| Mode | Input | Description |
|------|-------|-------------|
| **Size Mode** | Face photo + body measurements, or height + clothing size (XS–3XL) | Default mode — measurements-based body model. Measurement and clothing-size twins are eligible for estimated size fitting. |
| **Photo Mode** | Face photo + full-body photo | Body model taken from a full-body photo. Photo-mode twins are not eligible for estimated size fitting. |
## Authentication

- **Frontend app** (tryon.wearfits.com): Protected by Cloudflare Turnstile (bot protection), no API key needed for end users
- **Direct API calls**: Require `X-API-Key` header with key from [dash.wearfits.com](https://dash.wearfits.com)

## Rate Limits

| Context | Limit |
|---------|-------|
| Frontend app (per user) | 10 fittings/hour, 20/day |
| API (per key, job submission) | 50/min |
| API (job status polling) | 500/min |
