I am a chesty woman and finding a bra of any sorts has been a major headache.  I have been fitted but with the differences in all bras, I range from a 42DDD to a 42DD.  I ordered the 42DD since that was the largest I could and I am so delighted that I ordered two more.  This product is comfortable, flexible (I do yoga and clean houses) and fits well.  I have a drawer full of other sports bra but they have no support and give you the uni-boob look.  This provides great support and I don't muffin top out the front of it bending over and working.
