How it works
What actually happens when you tap try-on
A plain description of the mechanics: what the AI needs from you, what it renders well, what it genuinely cannot tell you, and where your photo goes.
What the app needs
- A base body — yours or a model’s. One clear, full-length photo of yourself is enough, set once and reused for every try-on. If you would rather not upload a photo at all, pick one of the built-in male or female models instead and skip this entirely.
- Garments. One piece, or a whole outfit layered across seven slots — outerwear, top, dress, bottoms, shoes, scarf, hat — taken from your closet or photographed from something you are considering buying.
- A moment. Generation runs in the cloud rather than on your phone, so each look takes a little time to come back.
What the AI is doing
In broad terms: it reads your pose and proportions from your photo, separates the garment from its background, and re-renders that garment onto your shape, matching the lighting of your original photo.
The important consequence is that the result is a generated image, not a photograph of you wearing the item. Nothing is measured. Nothing is physically simulated. It is a very good visual guess, and it should be read as one.
What it gets right
- Silhouette. Whether a shape suits your build — where a hem lands, how a cut reads on you.
- Colour against your skin tone. The single thing hardest to judge from a product photo on a model.
- Proportion. Whether a top and a bottom balance each other, or whether one overwhelms the other.
- Combinations. How two pieces you already own actually read together, without getting changed twice.
What it cannot tell you
Being straight about the limits, because they matter before you spend money:
- It is not a fit or size predictor. It will not tell you whether a medium fits. Use the retailer's size chart for that.
- Fine detail can drift. Small logos, printed text, and intricate patterns are the first things to degrade — check the product photo for those.
- Structured and very loose garments are harder. Tailoring, stiff fabrics, and heavy drape are the difficult cases for every AI try-on system, not just this one.
- It does not judge fabric or quality. Weight, texture, and how something moves are outside what a still render can show.
Getting a result worth looking at
The base photo does most of the work. If your try-ons look off, this is almost always why:
- Stand so your whole body is in frame, facing the camera.
- Use even light. Strong backlight or a hard shadow across you will be baked into every look you render.
- Prefer a plain background — it makes you easier to separate cleanly.
- Wear something reasonably fitted in the base photo. Baggy clothes hide the shape the AI is trying to dress.
- Keep a neutral pose, arms slightly away from your sides.
Where your photo goes
The shortest answer: if you use a built-in model, no photo of you is ever uploaded. What follows applies when you do use your own.
Photos are uploaded and processed in the cloud — this kind of generation is too heavy to run on a phone. They are stored under your account so you do not have to re-upload for every look.
They are not sold, and there are no ads in the app. Full detail is in the privacy policy.
How this differs from a shop's try-on button
Retailer try-on widgets only show you that retailer's catalogue, and stop existing once you close the tab. WearWhat works the other way round: your own wardrobe is the catalogue, and anything you are considering buying can be tried against it. The point is not to sell you the garment — it is to tell you whether you will actually wear it.
What it costs
The app is free to download and comes with a starter allowance of AI generations, which is enough to see whether the results are useful to you. A subscription — with a free-trial option shown in the app — unlocks continued use. Local pricing is shown in the app and in the store.
