How to find your size
Measure once, order with confidence. A practical guide to bust, underbust, waist and hip.

A well-fitting piece should sit flat against the body, stay in place when you move, and leave no deep marks. The measurements below are a starting point; the product page lists the sizes we actually stock for that style.
What you need
A soft tape measure, a mirror, and a fitted bra or no bra at all. Keep the tape level and snug, not tight. Write the numbers down in centimetres or inches, but use the same unit throughout.
Four measurements
- Underbust: around the ribcage, directly under the bust, with the tape exhaled and level.
- Bust: around the fullest part, usually across the nipple line, with the tape straight across your back.
- Waist: the narrowest part of the torso, usually just above the navel.
- Hip: the fullest part of the seat, usually 18–22 cm below the waist.

Bra sizing, without the maths
Subtract your underbust from your bust. The difference gives a rough cup: about 10 cm is AA, 12.5 cm is A, 15 cm is B, 17.5 cm is C, 20 cm is D, and 22.5 cm is DD. If you are between two sizes, take the larger band or cup that matches your larger measurement.
Between two sizes
For fitted bras and corsets, take the larger size. For loose slips and robes, take the smaller size if you prefer a closer line, or the larger size for a relaxed fit. If a style has no stretch at the waist, size to your waist rather than your bust.
What a good fit feels like
The band should stay level at the back. The centre front of a bra should sit close to the chest. A bodysuit should not pull at the shoulder or cut at the leg. If you need to pull a piece up all evening, it is probably one size too small.
