You take two photos in the mirror — one from the front, one from the side — and enter your height. From that we calculate your bust, waist and hip, and compare them with the measurements of the garment.

What happens to your photos

Nothing. They stay on your own phone or computer. The analysis runs in your browser, nothing is uploaded, and the moment you close the window the photos are gone. All we remember is your calculated size, and only on your own device — with a button to erase it.

How accurate is it?

In practice, a photo measurement is about three to five centimetres off. Enough for a size recommendation, not for tailoring. That’s why we always tell you how confident we are, and what your alternative is if you fall between two sizes.

Rather not use photos?

That’s fine. Answer three short questions instead: your height, the size you usually wear, and which stage you’re in. The advice will be a little rougher, but still useful.
