Other sports bras I have tried since being an H cup have been an absolute joke, and it was extremely frustrating finding something that would support me so I could zumba without the pain of the ladies bouncing all over the place.

I did a random search online, and found this bra (I ordered the Level 4 support).  I was surprised at the negative reviews on amazon, since they were so positive elsewhere.  It is a bit difficult to put on--but it's a sports bra, it is supposed to be very snug to hold you in.  And you are working out---I don't expect my boobs to look attractive in a sports bra that is holding them in so I can run and jump and dance.  If you think this sports bra is going to make your boobs look amazing, you need to lower your expectations and buy a supportive bra, not a cute one!

This is definitely worth the price.  The only negative is the fabric on the sides is a little scratchy--but that shouldn't bother you with a t shirt on.
