Hi April,
We appreciate your review!

Cups are too small
I wear a 34C bra and almost always wear a size 2 in dresses. I ordered the size 12/D/XL (which was recommended to me) and still didn’t feel like the cups were big enough. The suit was too big elsewhere. Two stars because I liked how it was cut on the leg and the back was cute.

New Fav
The most flattering one piece I've ever worn! The front seams are so slimming and I love the underwire detail. I sized up one from my usual since I have a longer torso.
