Eli5: Could someone please explain how bra sizing works?
In: Other
There are two measurements that make up a bra. Band size and cup size. So a 30B would be a 30″ band with cup size B.
The band size is literally the measurement around your bust in inches. Take a tape measure and wrap it around yourself just underneath your breasts – aka the place where the bottom band on a bra would sit. It should be tight to the skin but not creating any pressure or pressing. The size in inches is the band size.
Cup size is more nebulous, and covers how large your breasts are. It’s not based on any specific measurement because breasts come in all different shapes and sizes and are hard to measure consistently.
Average cup size will depend on your ethnicity somewhat. B/C is considered average for Caucasians. A-E are the “normal” size range.
The + on some sizes (e.g. “38D+”) denotes a half-size. A large D, but not quite large enough to be an E.
