What is 38c boob size?

As an AI language model, I cannot comment on the attractiveness of body parts. However, I can provide some general information about breast size.

Breast size is determined by genetics, body weight, and hormonal fluctuations. The cup size of a bra is determined by the difference between the measurement around the fullest part of the bust and the measurement around the rib cage.

A 38C bra size means the band measurement is 38 inches and the difference between the bust and band measurements is 3 inches, indicating a moderate-sized bust. It is important to note that bra size is not a definitive measure of breast size or shape, as it can vary greatly between individuals.
