Note to self on clothing sizes:
When the bathing suit retailer says 37" bust sizes should purchase a size 10, remember they're assuming a bigger rib cage (and not a 32" rib cage) and stick with the size 6 instead.
When the shirt retailer says 37" bust sizes should purchase a large shirt, listen to them.
The bathing suit will stretch over the breasts and look sexy. The shirt might stretch, but sexy?
Not so much.
