Band is stretchy for a 30 and cup doesn't fit my shape. The cup curves in and is for breasts that are more projected as opposed to shallow, I think. I found it to be a quintessential example of how push-ups don't usually work for shallow shapes!
I LOVE this bra. I just recently measured myself and have started rebuying my bra wardrobe. I was previously wearing a 32B which would gap and the band would ride up, and 32A was always too small. So far this is my favorite bra. I am measured to be around a 28D, but because of my shape, sometimes bras are a little too big in my size, but a size down would be too small.
This bra is perfect. I have shallow breasts that are wide set, so I enjoy a good pushup to give me some cleavage and a nice full round shape under a shit. This is the first bra that has no gapping when I wear it. It's a great shape and very lightweight, despite being padded. The band also fits snug on the second hook. I have been able to find more selection in a 30C than a 28D, and a 30C is much better for me than a 32B!
This bra is quite loose in the band and slightly too small in the cups for me. I would probably fit better in a 30DD in this model as far as the cup goes. However, this isn't a "good" push-up bra in that the padding inside distorts the tissue. I wear it only when I want to feel a little extra oomph.
