I ordered my normal size M and it fits really snug, however the top isn't loose and off of the shoulder like it is on the model. It is very comfortable and soft though.

I purchased this romper for work. It’s heavenly. Comfortable as heck. The only concern is that I’m afraid that if I dry it it will shrink and it’s maybe 1/2 a size snug. I’m 5’3 and weigh 140 and ordered a medium. Flattering, and converts well from casual to dressy.

Bought for my sister and she loves it.
