"This costume is great! I'm 5"11, 165lb and my measurements are Bust: 35.5, Waist: 29.5 and Hips: 38. I got the Medium and it's a great fit. I thought it would be too short but it's a lot longer than I was expecting, in fact long enough so that I can actually go out in public while wearing it (shock, horror!) It's strapless but it comes with a set of clear straps if you prefer them (it doesn't matter either way since the jacket would cover the straps). There's no zip, you just pull it over your head but it's no problem because the material is nice and stretchy. The hat is stretchy too and fits comfortably. I love camouflage and this is so perfect :) Great for the price."
