TRUE TO SIZE fits beautifully. I struggle with a good fit so this product has won ne over. Love the thick band as I need more coverage and support. Stunning. Have not washed yet.

Pretty, comfortable bra; small issue with cup structure
Size: 44D, Color: Black, Size: 44D, Color: Black
This is the first underwire bra I’ve worn in about six years - I’ve been wearing sport bras, so I wasn’t sure I’d like it.
This bra is pad free, lightweight, and made of very pretty lace. When I put it on, the underwire was not uncomfortable, and the bra itself fit relatively well. I was surprised that the band in the back was also comfortable, not digging into my skin. The bra is well-made with one exception. I think the top of the cup requires more structure. I feel that it’s a little too loose and the contents will fall out if I was to lean over too far or if I were to run or do anything slightly athletic.
I like the bra - it’s comfortable and pretty but it has that one issue with the cup structure. I’ve decided that this would not be a good bra to wear all day, but because it is so pretty, I would wear it with evening wear only.
