Its the best fitting bra I own so far. The cups fill out decently, with and without the inserts. That said, there are more than a few complaints. The straps only feel truly secure if I clip them into the racer-back mode. If I don't, they slide down and off the collar bone area. There is also a little bit of gap around the interior edges of the bra. Previously, I've found that the underwire tends to leave me sore after while, but I think tightening the straps down and fixing where the underwire hits has helped.
