What is the different between 36BB and 36B bra size?

The main difference between a 36BB and a 36B bra size lies in the cup volume. The "B" cup size indicates a specific volume, while the "BB" size denotes a slightly larger cup volume, typically equivalent to a B cup with added depth or fullness. This means that a 36BB bra generally provides more space in the cup compared to a 36B, making it better suited for individuals who may need a little extra room in that area. However, both sizes share the same band measurement of 36 inches around the torso.
