How to find your lingerie size (without a tailor)
Four measurements, one tape measure and ten minutes. Here is the method our fit team uses — and the three mistakes that make a well-made bra feel wrong.
Most people wear the wrong bra size, and almost nobody notices, because the wrong size still “works” — it just works less well. A band that rides up, straps that dig in, cups that gap when you lean forward: these are sizing signals, not body problems.
Start with four numbers
- Underbust, snug around the ribcage directly beneath the bust.
- Bust, around the fullest part, level with the nipple line.
- Waist, at the narrowest point, standing relaxed.
- Hip, around the fullest part of your seat.
Write them down in centimetres. Our size guide converts them straight into XS–XXL.
The three mistakes
Measuring over clothes. A knit adds 1–2 cm. Measure on skin, or in a thin bra you already trust.
Pulling the tape tight. Snug, not tight — you should still be able to slide a finger under the band.
Choosing panties by your dress size. Hip measurement is the only number that matters for panties. A size M brief and a size M dress are unrelated.
When you are between sizes
Size up in bras, because a firm band is doing the supporting work and it will relax slightly with wear. Size by hip in panties. For bodysuits, check the torso length note on the product page — if you are over 172 cm, our long-torso cut is the safer choice.
Still unsure?
