Why Our Fit Is Different
We surveyed 15,000 women before launching a single product and we're still listening.
Most brands start at a size 6. We start at size 12 - because that's where our customer actually is. We test every garment on two base sizes simultaneously: a 10/12 (C-Cup) and a 14/16 (E-Cup), across real women before a single piece goes to production.
Our fit model is 35 years old and 165cm - not a tall runway model. We then proof every garment on women in their 20s through to their 60s, across XS-3X, because ten size-12 women look completely different from each other.
Customer perception of fit always trumps the data. When our fabric ran small, we changed our sizing.
Every model's size and measurements are on site. Toggle between model sizes to see the garment on a body closer to yours. Real women, real sizes, on every product page.
Sizes XS-3X. Built for the body you actually have.
