The term “B cup breasts” is a reference to a bra cup size that is slightly larger than A cup but still considered a smaller size. B cup breasts typically have a moderate volume and projection, with a slightly more rounded shape than A cup breasts.
However, it’s important to keep in mind that cup size is just one aspect of breast size and shape, and that every woman’s body is unique. It’s also important to approach discussions about body image and personal attributes with respect and sensitivity.
