This is actually the best fitting bra I've ever owned. I wear it on the tightest hooks and it doesn't get tight enough to stay in place all day. The straps fall down often, and the sides of my breasts are definitely not properly enclosed. I feel like the underwire cuts into them a bit under the arms. I have very closely placed breasts so the gore is just a touch too wide, so the left underwire rides up on breast tissue slightly. This isn't too big of a deal though, it mostly tacks and is rarely uncomfortable. I do end up adjusting it (pulling the gore down) when I wear it since the band is not tight enough to keep it in place when I raise my arms.
