This is one of the most comfortable, carefree dresses I've ever owned. I received this three days ago and wore it to a wedding today. I didn't have to iron it or anything else, I basically wore it right out of the package. It is flowy and I felt amazing in it.
I'm 5'4", 148 lbs, 38B, size 8 top and 10 pants, and the size medium is perfect for me in every way. 10/10 recommend!
