It's a lovely bra, very comfy, but fits small. I fit Belabumbum's 36D perfectly and ordered this in a medium. I couldn't even get the hooks closed and I was spilling out everywhere. Even the large is a bit snug for my preference but it's too pretty to send back and it should be ok once the last few pounds are off!
The sizing is not accurate at all for this bra. I should have been a large, but the XL is still too small for me. I think that if you have really full round breast that this bra won't ever fit probably for you ( which most nursing woman would).
This bra is dressy, yet comfortable with adjustable strap placements in the back and a full range of hook and eye closures. It is supportive (at a 38 F), provides an excellent fit, plus it is so pretty.
