The material is soft and has a nice flow to it when you walk. I also like the thickness of it. It isn't see-through, but it isn't heavy. It also looks like wrinkles won't be much of a problem.
I am 5'6, and the dress went to my ankles, which was perfect for me. I got a medium, and it seemed to fit true to size. If you are larger chested, I would size up.
