First jumpsuit ever since it is easy for jumpsuit to look too child-like or costumy for me. I'm into this one though. The fitted waist and slim arms/legs makes it flattering and more sophisticated, and it's comfortable. They run big. I'm 5'1" and usually wear a U.S. 4 /6. The U.S. 2 fit me best. My only suggestion is I don't like the big logo patch that stands out on the back and I wish there were petite lengths.
