đ Understanding Bra Sizing
Incorrect Bra Fit
Surveys and studies often cite that anywhere between 70-85% of women wear incorrectly fitted bras. The most common mistake is choosing too large a back band and too small a cup.
Some signs of incorrectly fitted bras include the band digging into the torso or sliding upwards, red marks, shoulder or neck pain, and the breasts overflowing around the edges of the bra.
Band Size (Frame Size)
The band size is the size of the bra band around the torso. Band sizes come in different measurements in different countries.
| Size | US/UK | EU |
|---|---|---|
| XS | 30 | 65 |
| S | 32 | 70 |
| M | 34 | 75 |
| L | 36 | 80 |
| XL | 38 | 85 |
Cup Size
The cup size can be calculated using the difference between bust size and band size. Refer to the tables below.
