I bought this bra for riding my horse to minimize the bounce.  I normally wear a 38D the cup size was perfect. The band is loose on middle hooks, so will order a 36D to see if that makes a difference.

I only wish 2 things:
1. That the straps were a bit more narrow so you can wear a tank top w/o straps showing.
2. That the cups had some more padding to allow for better coverage.(I bought some nippies they help)
