I just received this item and I'm very happy with the fit. I had read reviews and I was afraid the cup size would be ridiculously big. My size for bras is 36 D or C when the cups run big. I don't have a very full bust for a D but Cs usually cut me. Often my bust is spilling out of strapless bras but not with this. You see less bulge than in the photo. I ordered this in 36 C. It fit very attractively, also the waist wasn't exaggeratedly tight. I've been looking for this type bra in France and in the US for over a month. It's not easy to find. I bought this to go under a sheer topped cocktail dress, to look like a built in bodice. The dress came with an attached camisole that looked flimsy. This looks very attactive under the dress, not like a bra but like a refined finishing under  the sheer silk.  I didn't have much bulge at the waist as the reviews had warned, but if this were 3 inches longer there wouldn't be any. I'm tall and it is shorter than I had hoped.

 As for their other plunge longline I bought it too thinking it would be lower and might work better. It wasn't. It's exactly the same model, without the microfiber which gives the invisible effect, same length, but the waist is nearly 3 inches smaller. It's way too tight!
This is a much nicer bra. I'm thinking about buying it in ivory also to go under other sheer tops. I really was afraid that buying this would be a mistake and was pleasantly surprised. Also it arrived just in time.
