Not very flattering
I'm 145 lbs, 5'6", and I usually a size 8 in most things. I ordered a Medium. I like the fabric alright, the belt is okay, and parts of the dress are alright, but it just wasn't very flattering, especially for over $100.
The hemline was about an inch shorter than I would've liked and you can see right through it! I stood in front of the mirror and could see right between my own legs.
So, I'm returning it.
