Rated 2 out of 5 by from Poor fit It's a beautiful bra, but the fit is really bad for me. The mesh parts bunch up and the cups have a weird, triangular shape. A real shame as it's a beautiful bra...

Rated 2 out of 5 by from Fits Beautifully, but Slight Staining from Lace This bra fits beautifully and feels very comfortable. As someone with a fuller bust, I was pleasantly surprised by how well supported I feel the cups hold nicely without being overly padded. It’s a pretty and flattering design that still offers great comfort. However, I did notice that the sheer lace section at the top of the bra left a faint black stain on my skin. It wasn’t intense and washed off easily, but it did catch me off guard the first time. Overall, I’m very pleased with the fit and quality just a bit disappointed about the minor staining issue.
