I have FOB, wide root, rather shallow breasts. There was a bit of gaping at the top of the cup, but not too bad. The straps were wide set but did not irritate like others I have tried in a similar style. The problem with this bra for me was the underwires. They weren't' wide enough and dug in to the breast tissue at my underarms. After a few hours of wear, I had to take it off.
The information of this bra is not concerning me but a friend. With her measurment, her size a 32DD. She want absolutely a red bra and I find this one. Fortunately, I bought the same model in 32D and 34D. The 32D was too small in the cup and the band size. We was lucky, the 34D fit perfectly to her. She really likes this bra. Very pretty, confortable.
