I wore this with a semi-plunging dress and even though the material didn't work very well (velvet), the bra was great! It gave me a decent amount of cleavage, which I'm not used to since I'm a 36A/34B. I can't wait to start looking at dresses that have more intrigue now that I have this bra to feel comfortable in!
I am a 32 B & I purchased a 32 C. The website recommended to go up a cup size b/c it runs smalls but it should have also mentioned how small the band runs. I had it on the very last hooks & it was extremely tight, I had a red ring around my rib cage only wearing it for 2 minutes. I would imagine that it would be a size 28 if there is such a size but it's definitely not a standard US size 32. The cup area was okay, it didn't really contour to the breast as much as I would have liked. After 3 kids & yrs of breast feeding, a little lift goes a long way & this bra didn't do that for me.
I'm a 34D and these bras typically do not support me. This one is tight, secure and supportive. I was pleasantly surprised that it did the job and was very affordable. Back fits normally, cups are as small as they look in photo so there will be some spillage (by top / armpits) but my dress covered it.
