[Bone011]

So I Brought My First Bra Today And I Think It Fits I Dont Know The Size Because I Bought The Bra Off A Website Called Wish. 
And The Sizes Just S,M,L & Xl. So I Chose Small ( Which I Know Is An A). But I Dont Know Which Number Like 33, 36 or Something. And Do Bra's Grow Our Breast Or Just Keep Them In Place? And Do You Guys Where Yall Bras To Bed?

To measure your bra size, put a tape measure around your chest underneath your breasts. It's probably the same as your waist size plus a few inches. That tells you your band size.
The bigger measurement is at the widest point, around your nipples. The difference between the two measurements tells you your cup size. A 1-inch difference is an A cup, a 2-inch difference is a B cup, 3-inch difference is a C cup and so on.
My chest measures 42 inches around under my breasts and 45 inches around them, so I'm a 42C.
