When I first took it out of the package and held it up, it looked so huge and wide I almost sent it back w/o even trying it on. But glad I went ahead and gave it a chance. It is relaxed but hangs in a flattering way and the material is so nice and soft and thin but not sheer. I’d say go with your normal size if you like the way it fits the models. (I’m 5’8”, 150, went w my usual size M) The neck is not cut too low, which I love. The dark navy is a great color. Am going to be able to wear this lots of places and for just lounging. Hope to order another color if this dress goes on sale.
