Looking beyond virtual try-on tools?
Single garment swap is the demo. Full aesthetic capsules are the product.
About Virtual Try-On (IDM-VTON, OOTDiffusion, CatVTON)
Open-source virtual try-on (VTON) models — IDM-VTON, OOTDiffusion, CatVTON — let you place a single garment onto a single person photo. They're the academic ancestor of consumer outfit-swap tools.
Open-source virtual try-on (VTON) models — IDM-VTON, OOTDiffusion, CatVTON, VITON-HD — have been the academic backbone of consumer outfit-swap for years. IDM-VTON in particular (ECCV 2024, 4.6K GitHub stars) is the most-cited diffusion-based VTON. Run on Replicate at ~$0.025 per generation, ~19 seconds per output.
These tools are excellent for one thing: swap *one specific garment* onto a person photo with reasonable fidelity. They're not built for *outfit composition* — top + bottom + shoes + accessory + scene + mood + lighting. Our r3-B bakeoff put IDM-VTON's nearest cousin (Leffa) at 3.4/5 vs Google's nano-banana-pro at 4.6/5 for outfit-swap quality.
ChangeOutfit's product is the capsule, not the garment swap. Old Money isn't a single garment — it's an Aran knit + corduroy + loafers + manor drive + golden hour + restrained warm palette. Forty-one such capsules, curated. The pipeline behind it uses the same model family as VTON tools, but the orchestration is editorial. You don't pick a sweater; you pick a vibe.

The honest verdict
Pick a VTON tool if: you're a developer building your own outfit app, you have specific control needs (per-step segmentation, custom training), or you're prototyping. Pick ChangeOutfit if: you want to be a user not a developer, you care about full outfit composition rather than single garment swap, and the editorial capsule curation matters more than raw model access.
Frequently asked
questions.
Do I have to train an AI model of myself?
No. One photo, ten seconds. Other tools make you upload 20+ selfies and wait — we skip that. Your face stays your face; only the outfit and scene swap.
How does the outfit swap actually work?
Upload a full-body photo. Pick a capsule or a single look. The AI lifts the outfit + scene from the capsule onto you, keeps your face. Each look takes about ten seconds on Seedream-4.
What's a capsule?
Five looks built around an aesthetic. Mini-collections, basically. We have 41 — Old Money, Quiet Luxury, Mob Wife, Coquette, Hot Girl Summer, Country Girl, Cool Girl Downtown, plus 34 more. Full library at /app/collections.
Will it actually look like me?
Yes. We pin the model down explicitly: keep face, eyes, age, hair color, hair length, skin tone, body. Only clothing + lighting + scene change. If the first result drifts, run it again — natural variance lands different each time.
What does it cost?
Five free credits a day, no card. After that, Pro is $9.99/mo (200 credits) and Premium is $29.99/mo (600 credits) — or grab a one-time credit pack from $4.99. Each look = 1 credit. A full 5-look capsule run = 5 credits.
What about privacy?
Your photos sit in private storage scoped to your account. We don't train shared models on what you upload — every generation is one-shot. Delete anything anytime from /app/media-library; the storage object goes too.
Can I use the outputs commercially?
Yes on Pro and Premium. The free Day Pass is personal-use only. The AI step doesn't change ownership — your photo stays yours.
First try looked off. Now what?
Re-run the same look — there's natural variance and the second pass usually lands cleaner. Magic Edit (coming soon) will let you describe a tweak ("longer coat", "swap the background to a hotel lobby") in one sentence.
How do I save the ones I like?
Tap the heart on any generation in /app/designs. Favorites surface across the app — including in the related-looks footer of each capsule page.
