Shopping with confidence
Most of our pieces are designed in a single, generously cut size. Here's everything you need to know to find pieces that'll work beautifully for you.
our honest fit guide
our sizing philosophy
One size - designed with real women in mind
We know that shopping for "one size" clothing online can feel like a leap of faith. So let's be completely honest with you: our pieces aren't designed to fit every single body — but they are designed to fit a wide range of shapes and sizes beautifully, with fabrics that move with you and cuts that are forgiving in all the right places.
Our team — all women — try every piece before it reaches the site. If we don't love how it fits, it doesn't make the edit. Where a piece has a narrower fit range, we say so clearly in the product description.

How To measure yourself
A soft tape measure and two minutes is all you need. These are the measurements that matter most when shopping our range — and we reference them in every product's Size & Fit section.
1
Bust
Measure around the fullest part of your chest, keeping the tape parallel to the floor. Don't pull tight - breathe naturally.
2
Waist
Measure around your natural waist - the narrowest part of your torso, usually just above your belly button.
3
Hips
Measure around the fullest part of your hips and seat, usually about 20cm below your waist.
4
Height
Stand straight without shoes. This helps you judge whether a hem length will work for you - we notes model heights on every products.
Our top tip: If you're between sizes or unsure, always check the flat measurement in the product's Size & Fit section and compare it to a similar garment you already own and love. This is far more reliable than sizing by label alone.
