Slinkedog, is your bra cotton? It could be a heat rash, I have to have a cotton blend or no cotton, I wear a 36D also, when I run I usually wear 2 bras as I haven't found one with enough support.

I have a friend who is an excellent seamstress and we are working on designing a "real" supportive bra for "bustier" women. I have several different types of sports bras and I am trying to find the combination that best holds everything, I think I have it, so now we are trying to find the moisture wicking fabric - most of them we can't get our hands on tho.

I do want to try underarmor's sports bra before making a decision, it looks supportive BUT the problem with almost all of them are the straps, the bra will hold you up but then the straps let you flop all over.


Let me know if ya'll have any ideas!!
