I normally wear a 34G but a 32H was a better fit in this bra.  I loved the fact that it doesn't have underwires and was comfortable.  At first, it was very supportive but after wearing it around the house for several minutes, it lost its support.  I was so excited at first because I felt like I could actually run in this bra but after only a few minutes it loosened up and no longer acted like a sports bra :(
