# Flux Klein 9b Virtual Try-On LoRA

Virtual clothing try-on LoRA for [Flux Klein 9b Edit](https://fal.ai/models/fal-ai/flux-2/klein/9b/base/edit/lora). Given a person image and clothing reference images, generates a realistic result of the person wearing the specified outfit.

**3 input images** (person, top, bottom) **→ 1 output** with the person wearing the clothes.

Built with [fal.ai](https://fal.ai)

| `flux-klein-tryon-comfy.safetensors` | ComfyUI |

## Recommended Settings

| Parameter | Value |
|-----------|-------|
| `num_inference_steps` | 28 |
| `guidance_scale` | 2.5 |
| `lora_scale` | 1.0 |

## Usage

### Try It Online

The easiest way to try this model:

- **[Playground (direct)](https://fal.ai/models/fal-ai/flux-2/klein/9b/base/edit/lora?share=6010a961-502a-437a-974f-88c48730bf5d)** — upload 3 images and write the prompt yourself
- **[Workflow with LLM](https://fal.ai/workflows/lovis/workflow-flux-klein-9b-virtual-tryon?view=playground)** — upload 3 images and the LLM auto-generates the prompt

### Python (fal-client)

```python
import fal_client

result = fal_client.submit(
    "fal-ai/flux-2/klein/9b/base/edit/lora",
    arguments={
        "prompt": "TRYON young woman with long dark hair, standing casually. Replace the outfit with red hoodie and blue jeans as shown in the reference images. The final image is a full body shot.",
        "image_urls": [
            "https://your-person-image.png",    # 1st: person
            "https://your-top-image.png",        # 2nd: top garment
            "https://your-bottom-image.png",     # 3rd: bottom garment
        ],
        "loras": [{
            "path": "YOUR_LORA_WEIGHTS_URL",
            "scale": 1.0,
        }],
        "num_inference_steps": 28,
        "guidance_scale": 2.5,
    }
).get()

print(result["images"][0]["url"])
```

## Tips for Best Results

- **Describe the person** accurately in the prompt (hair, pose, body type)
- **Describe the clothing** in detail (color, pattern, style, material)
- **Full body shots** work best — mention "full body shot" in the prompt
- **Clean backgrounds** on input images improve results
- **Consistent lighting** across the 3 input images helps
- The trigger word `TRYON` must be at the start of the prompt
- Keep `lora_scale` at 1.0 for best results
- Works with both photographic and AI-generated input images
