I am G/H+ cup (nursing a 3 month old) right now and want to get back into the gym. I am on the hunt for a sports bra that will support my large chest and is very comfortable for kickboxing. Bonus if I can find it in store and try it on....I've had no luck with purchasing online. I have a small rib cage so none of the sports bras that aren't bra-sized (S, M, L, etc) fit me right....

Anyone else a similar size and have one they can recommend?
