Virtual Outfit Try-On with Auto Segmentation Using Flux Dev in ComfyUI

You have a clothing item. You have a subject. You want to see the outfit on that person, cleanly, realistically, without manual masking.

Outfit image and subject image in. Virtual try-on out.

Run it now on Floyo!

How It Works

Upload your outfit image and your subject image. Human Parts Ultra automatically segments the body regions the clothing should apply to no manual masking required. Flux Dev with Ace Plus and Redux handles the transfer, fitting the garment to the subject while preserving their identity, pose, and proportions.

Three models working together:

Flux Dev: The base generation model. Handles photorealistic output and overall image quality.

Ace Plus: The outfit transfer layer. Reads the garment structure, fabric, and design from your reference and applies it to the subject.

Redux: Reinforces visual consistency between the outfit reference and the generated result. Keeps the garment recognizable across the transfer.

Human Parts Ultra: Automatically segments the target body regions. You select which parts the clothing covers. The model uses those segments to align the garment correctly during generation.

Key Inputs

Outfit Image

The garment you want to transfer. Use a high-quality reference, visible artifacts, distortions, or compression in the outfit image carry over into the output.

Works well with:

  • clean catalog or product shots of the garment

  • flat-lay or ghost-mannequin photos

  • well-lit, front-facing clothing shots with readable fabric detail

Works less well with:

  • heavily compressed or blurry garment references

  • outfits with extreme motion blur or heavy wrinkles obscuring the design

  • very dark garments against dark backgrounds with no contrast

Subject Image

The person or character you want to dress. Clear and front-facing produces the most accurate fit.

Works well with:

  • clean portrait or full-body shots

  • front-facing or slight angle poses

  • subjects with clearly visible torso and arms

Human Parts Ultra Body Region Selection

This is the critical setup step. Choose which body parts the clothing should apply to based on what the garment actually covers.

Examples:

  • Long-sleeve shirt: select torso, left arm, right arm

  • T-shirt: select torso only

  • Jacket: select torso, left arm, right arm

  • Trousers or skirt: select left leg, right leg

  • Full outfit: select all relevant regions

Selecting the wrong regions produces misaligned results. Match the selection to the actual coverage of the garment.

Prompt

Default value works for most outfits. Adjust it if you want to steer the output toward a specific style or material treatment.

Examples:

  • "subject wearing the outfit from the reference image, natural fit, realistic fabric, consistent lighting"

  • "realistic virtual try-on, garment fitted naturally to subject, preserve face and pose"

  • "fashion try-on, fitted casual outfit, soft studio lighting, clean background"

What This Is Great For

Fashion and e-commerce mockups: Preview how a garment looks on different subjects without a photoshoot. Generate multiple model variants from a single garment reference.

Concept and character styling: Quickly test different outfit combinations on a character or subject for design development, game art, or pre-production work.

Lookbook ideation: Combine garment references with model references to generate lookbook imagery for presentations and client approvals.

Retail product visualization: Show clothing on a variety of subjects to demonstrate fit and styling across different body types and aesthetics.

What to Watch Out For

Outfit image quality is the most important input. A blurry or artifact-heavy garment reference produces a weak transfer. Use the cleanest product shot you have.

Body region selection must match the garment. A long-sleeve shirt selected with torso only will produce sleeves that don't transfer. Take a moment to correctly map the garment coverage to the Human Parts Ultra selection before running.

Complex layered outfits (jacket over shirt over accessories) are harder to transfer in one pass than single-piece garments. For layered looks, consider transferring one layer at a time.

Very loose or heavily draped garments with no defined shape are harder to fit accurately. Structured, well-defined garments with clear silhouettes transfer most reliably.
