This is why two women can both wear a "B cup" but appear to have very different chest sizes. Many women wear the wrong size for years, unaware that a few inches of band or cup difference can dramatically change how a bra feels and functions.
Cup Size Relative To Band Size Truth: Understanding Volume Differences
The band size is typically an even number, such as 32, 34, or 36, and this number corresponds to the measurement in inches. A balconette bra, which sits low on the chest, might fit differently than a full-coverage T-shirt bra.
If your bra band rolls up in the back, the band is likely too loose and you need to go down a band size while maintaining the same cup size, or go down a band and up a cup to account for the volume shift. The difference between the two measurements dictates the cup letter; for example, a 1-inch difference usually corresponds to an A cup, a 2-inch difference to a B cup, and so on.
Cup Size Relative To Band Size Truth: Understanding Volume Differences
An A cup on a 32 band is significantly smaller in volume than an A cup on a 40 band. For the bust measurement, wrap the tape around the fullest part of your chest, keeping it parallel to the floor to capture the true volume of your upper torso.
