WTf is a cup size?!, women don't have cups...cups are for pouring drinks into them......I don't get it....

Cups are like breasts.
They have liquid inside and people drink from them.
Is logical.

"The fabric that surrounds and supports the breasts."

That is the cup.

cup size is the size of your bra where your breasts go. and its probably called a cup size because of the way its shaped. 또는 cuz ur breasts hold liquid.
