Bra size

Bra size is a measurement used in the lingerie industry to denote the size of a woman's bra. It is typically represented by a combination of a number, indicating the band size, and a letter, indicating the cup size. The bra size is calculated based on the circumference of the woman's torso at the bust and under the bust.

Measurement

The band size is measured by taking the circumference of the woman's torso directly under the bust. This measurement is then rounded to the nearest even number to determine the band size. The cup size is determined by measuring the circumference of the bust at its fullest point and then subtracting the band size measurement. The difference between these two measurements corresponds to a specific cup size, with each inch difference representing a different cup size.

Sizing systems

Different countries and brands use different sizing systems for bras. The most commonly used systems are the UK sizing system, the US sizing system, and the EU sizing system. These systems differ in the way they calculate band size and cup size, and in the letters they use to denote cup sizes.

Fit

Proper bra fit is crucial for comfort and support. A well-fitting bra should have a band that fits snugly around the torso, cups that fully encase the breasts without causing bulging or gaping, and straps that do not dig into the shoulders. Many women wear the wrong bra size, often due to incorrect measurements or variations in sizing between brands.
