Trying on clothes before buying them online

A virtual fitting room uses artificial intelligence to generate an image of how a garment looks on you from your photo. Werop items can be tried on this way in Chulair. This is what it does, what it does not do and how it works.

In short

A virtual fitting room uses AI to generate an image of how a garment looks on you from a photo of you.
Werop items can be tried on in Chulair, the virtual fitting room app from the same team.
It helps you decide whether you like it on you: colour, length, style. It does not choose your size for you.
Werop does not receive your photo: it stays in Chulair.

The problem: buying clothes without being able to try them on

In a physical store you try on three garments and take one. Online you cannot, so many people buy two sizes or three colours “just in case” and return the rest. It is inconvenient for the buyer, expensive for the store — especially a small one — and absurd for the planet: parcels going back and forth.

An independent brand suffers from it more than anyone. It does not have the volume of a large chain to absorb returns, and you have not seen its garments on anyone in the street: there is no prior reference for how they fit.

How a virtual fitting room works

The technology is called virtual try-on. An artificial intelligence model receives two images — a full-length photo of you and the photo of the garment — and generates a third: you wearing that garment, respecting your posture, your build and the approximate drape of the fabric. It is not a cut-out pasted on top: the AI reconstructs folds, shadows and proportions.

What it does well

Showing you the colour on your skin tone and with your hair, which is where catalogue photos mislead the most.
Giving you an idea of the length and volume: whether that coat reaches your knee or your ankle.
Letting you see the style on you and not on a model who does not look like you.

What it does not do

It does not measure you. It does not know whether you need an M or an L: that is what the size guide and the store's measurements are for.
It does not guarantee the real fit or the feel of the fabric. It is an indicative simulation, and we say so in our terms as well.

Werop and Chulair

Chulair is a virtual fitting room app with artificial intelligence. Werop was born inside Chulair and in May 2026 became a project of its own, with the same team behind it. The integration between the two works like this:

The Werop catalogue appears in Chulair, with filters by type of garment, gender and colour.
You choose a garment and try it on over your photo.
If you like it, you move to Werop to buy it directly from the brand that makes it.
You can link your Chulair and Werop accounts, and undo the link whenever you want from “My account”.

Your photo does not leave Chulair. Werop only shares its catalogue of garments; it never receives or stores the images you use to try on clothes.

Tips for a good result

A full-length photo, from the front, with good light and an uncluttered background.
Fitted, plain clothes in the starting photo: the AI works better than on loose or patterned garments.
Arms slightly away from the body, with no bags or objects in front.
Use the try-on to decide whether you like it; for size, always look at the measurements.

Frequently asked questions

What is a virtual fitting room for clothes?

It is a tool that, from a photo of you and a photo of a garment, uses artificial intelligence to generate an image of how that garment would look on you. It helps you decide before buying online: seeing the colour on your skin tone, the length, the style and how it goes with other things.

Does the virtual fitting room tell me which size to buy?

No. A virtual fitting room is an indicative simulation: it helps you see whether you like the garment on you, but it does not measure your body or guarantee the fit. For size you need to look at the size guide and the measurements given by the store.

How does Werop's virtual fitting room work?

Werop does not have a fitting room of its own on the website: it is integrated with Chulair, a virtual fitting room app with artificial intelligence from the same team. The Werop catalogue appears inside Chulair, where you can try the garment on over your photo and, if you like it, go on to buy it on Werop.

Does Werop see or store my photo?

No. Your photo is uploaded to Chulair and handled by Chulair according to its privacy policy. Werop does not receive it: the only things that travel between the two platforms are the garment catalogue and, if you decide, the link between your two accounts, which you can undo whenever you want.

Does trying on clothes virtually reduce returns?

That is the idea. Not knowing how a garment will look is one of the main causes of returns in online fashion. Seeing it on you before buying avoids some of the “just in case” purchases, although it does not replace a good size guide.
