How to measure

WAIST: Simply run a tape measure around the narrowest part of your waist. Place one finger between your body and the tape measure to ensure a bloody comfy fit.

HIPS: Run a tape measure around your hips, 20cm below the waist. Place one finger between your body and the tape measure to ensure a comfy fit.

BUST: Run a tape measure around the fullest part of your bust, without a bra. Keep the tape level and slightly relaxed.

CHEST: Run a tape measure around the widest part of your chest. Keep the tape level and slightly relaxed.


Size variation

All of our garments are hand-made at our workshop by real humans, not robots, so there can be a small variance from pair to pair. We have to allow for a small difference between garments since everything is hand-sewn, but never enough that it’s uncomfortable!
