Never thought i would buy a jumpsuit, but this one is gorgeous. i put true to size. i ordered a m and a l. i kept the l because i like the looser fit. weigh 150# and am 5' 6 1/2" tall. i carry any extra weight at my waist and the l just looked better. i almost always wear a m in retailer clothes. love the feel of it and the way it looks on me. really looking forward to wearing it. on sale it is a great buy.
