NIUD Boosters Size Guide
Quick answer: find your everyday bra band and cup in the chart below. The letter is your NIUD Boosters size. If you are between sizes, size down for a more natural lift.
Size chart
Band sizes are in inches (UK and US), with the usual EU and Asian band in brackets. Cup letters are UK and US. A dash means we do not make a size for that fit yet.

Before you order
- Boosters need an outfit that holds its own shape: boning, cups, a firm lining or thick fabric. They do not work in soft or stretchy fabric.
- They add lift and volume inside your outfit. They do not replace a bra.
- Do not wear them with NIUD Covers. The two are not designed to be worn together.
Shop NIUD Boosters or read the strapless and backless guide.
