Let’s find your perfect fit!
Right Measures for Right Size
1. Wear a non-padded bra—and bust out your measuring tape
Wear an unlined or contour bra (no push-ups or sports bras) while taking your own measurements for the most accurate results.
2. Measure your ribcage
The measuring tape should be wrapped around your back, with the ends facing forward and overlapping in front. Your bust should be the centre of the tape measure, which should also be parallel to the floor and fit but not too tight.
3. Measure your bust
The measuring tape should be wrapped around your back and brought forward to overlap across the front of your bust, where it is the fullest. The tape measure should be snug but not too tight, parallel to the ground. In order to determine your cup size, multiply this amount by your total bust measurement.
4. With these measurements in mind, use our reference charts below to find your band size and cup size ⤵
Use the Swing Size Chart below as a quick reference when deciding whether to go up or down a size to get the right fit. If your underbust measurement is a 32B, switching to a 30C bra will offer you a slightly firmer fit. You'll get a looser underbust fit if you switch from a 32B to a 34A bra.
The most common fit concerns and recommended solutions
Band pulls up at the back
When the band pulls up at the back, the cups seem fine; the body size may be too large. Consider going for a smaller body size and perhaps a larger cup size (e.g. 32B becomes 32C).
Band is digging in
If the band is digging in, but the cups are okay, the body size is probably too small. Try a bigger band size and a smaller cup size (e.g. 34B becomes 36A).
Straps slip off shoulders
The body size is too large if the strips come off your shoulders, yet the cups fit well. Consider going for a smaller body size and a larger cup size (e.g. 34B becomes 32C). Try models with racerbacks or straps that are wider and more substantial.
Cups are wrinkled
If your bra cups are wrinkled, but the band fits comfortably, the cups are probably too large. Change to a smaller cup size (e.g. 34B becomes 34A).
Breasts are spilling out of cups
If your breasts spill out of cups, but the band still fits comfortably, the cups are probably too small. Change to a larger cup size (e.g. 34B becomes 34C).
Underwires are poking the breast
The cups are likely too small if the underwires irritate you, but the band is comfortable. Choose a larger cup size or a minimiser style to accommodate a wider breast form.
Underwires don't sit flat on the body
The cups are probably too small when the underwires don't sit flat on the body, but the band fits well. Change to a larger cup size (e.g. 34B becomes 34C).
