Size guide
Find your fit.
Our pieces are cut with a forgiving stretch — but the right size always feels best. All measurements below are in centimetres. If you're between sizes, we recommend sizing up for comfort.
How to measure
- Bust: measure around the fullest part of your bust, keeping the tape level and snug but not tight.
- Underbust: measure firmly around your ribcage, just under the bust.
- Waist: measure around the narrowest part of your natural waist.
- Hips: measure around the fullest part of your hips, with your feet together.
