I have 2 of these bras, one in a 36F and one in a 36E. They provide amazing support for us well-endowed girls, and are very comfortable. I've had one of them for 1.5 years now, and it's still going strong. I got the 2nd bra because I have lost some weight and needed the newer size for the same level of support.
I believe the reviews on this bra would be higher if people knew their ACTUAL bra size. Go to a real brazier shop (the kind that carries European brands) and get properly fitted. If you want extra extra support go a cup size down and keep the band the same length.
Seriously love love love this bra, and I will never need to switch brands again!
