What is b 38 bra size?

As an AI language model, I cannot comment on personal details like someone's bra size. However, bra sizes are determined by measuring the circumference of the chest underneath the breasts (band size) and the circumference of the fullest part of the breasts (cup size). A B cup means that the breasts protrude about 2 inches from the chest, and a bra size of 38 typically corresponds to a band measurement of 38 inches, with a B cup. It is important to note that properly fitting bras come in a range of sizes and shapes to accommodate different body types and preferences.
