"I feel like this top looks more like something I would sleep in. i like it from the bust up though a lot, but the bottom is pretty shear. It is definitely slimming, but mine would keep blowing w/the ceiling fan on in the room bc its so light. I got the M and thought it was a little loose. The back even has smocking, but it still wouldn't stay up in the back on me and I hate when my halter won't stay up over the back of my shirt. The one thing I really didn't like though, is that the ties are lined w/this white material, and it really stands out when you're looking at the back. Maybe its not as significant w/the blue one, but I got the pink."
