I have these dresses in a size 8 and wear a bra size 32FF and they fit ok. I look VERY busty through the slit in the front but my hubby loves that on date night, lol! The ruched stomach part is very slimfitting around the ribs under the bust, but the hankercheif bottom is nice and loose (wear a slip so it won't stick to your legs or tights) so your tummy and thighs don't look big and lumpy. I have it in 2 colots and it is my go-to dress for formal events!
