How to Combine Separate Garments into One Outfit with AI Mix & Match

Have you ever wanted to see how two separate garments look together on a model — without scheduling a photoshoot? Whether you're a fashion brand building lookbooks, an e-commerce seller creating outfit bundles, or a designer exploring combinations, StyTrix's Mix & Match tool lets you combine individual garment photos into a complete, photorealistic outfit in seconds.

In this tutorial, we'll combine a black essentials t-shirt and a pair of beige khaki pants into a single model image.

What You'll Need

• A StyTrix account (free tier works)
• Two or more garment images (flat-lay product photos work best)
• A short text prompt describing the desired look

Download top (black t-shirt) · Download bottom (khaki pants)

Step 1: Create a New Project

From the Dashboard, click the New Project card to create a fresh canvas.

Step 2: Open Mix & Match

In the left sidebar under Core Generation Tools, click Mix & Match. This opens the Mix & Match panel where you can:

• Upload multiple garment images (top to bottom, outer layer to inner layer)
• Set aspect ratio and output size
• Write a prompt describing the desired outfit look

Tip: Place your reference images in order — top to bottom, outer layer to inner layer. For best results, use images over 1080px.

Step 3: Upload Your Garment Images

Click Browse to upload your garment photos. In this example, we upload two images:

1. Black essentials t-shirt — the top layer
2. Beige khaki pants — the bottom layer

Both images show as "Reference image" with thumbnails confirming successful upload.

Step 4: Write Your Prompt

In the Prompt field, describe how you want the outfit to look on a model. Be specific about style and setting:

A young female model wearing a black essentials t-shirt paired with beige khaki pants, casual streetwear style, clean studio lighting, full body shot

Tips for better prompts:

• Describe the overall vibe (casual, editorial, streetwear, etc.)
• Mention lighting and shot type (full body, half body, etc.)
• Keep it concise — the AI works best with clear, focused descriptions

Step 5: Generate

Click the Send button (costs 10 credits per generation). The AI will analyze both garment images and your prompt, then generate a photorealistic image of a model wearing the complete outfit.

You'll see a progress indicator while the image is being generated (approximately 20–30 seconds).

The Result

Here's the final output — both garments seamlessly combined on a model. The AI has:

• Preserved the exact appearance of both the black t-shirt and khaki pants
• Generated natural model posing with appropriate body proportions
• Applied clean studio lighting consistent with the prompt
• Created a production-ready image suitable for lookbooks, e-commerce, or social media

Use Cases for Mix & Match

• Social media content — Create styled outfit posts for Instagram, Pinterest, or TikTok
• Pre-production planning — Visualize fabric and color combinations before manufacturing
• Personal styling — Help customers see how pieces from your catalog work together

What's Next?

Once you have your combined outfit image, you can:

1. Iterate — Swap out garments, change the prompt, or try different model styles
2. Upscale — Use the Upscale tool for higher resolution output
3. Remove Background — Clean up the image for a white or transparent background
4. Video Generation — Turn your outfit image into a short fashion video
5. Add more pieces — Upload 3+ garments (jacket, top, bottom, shoes) for complete outfits

Pro Tips

• Image order matters — Upload garments top to bottom, outer to inner. The AI uses this order to layer garments correctly
• Use flat-lay or product photos — Clean product images with white/plain backgrounds give the best results
• Mix categories freely — Combine tops, bottoms, jackets, accessories, and shoes in a single generation
• Try different prompts — The same garments can look very different with different prompt styles (editorial vs. casual vs. streetwear)
• Batch generate — Increase the count next to Send to generate multiple variations at once
