I love my jumpsuits, and I purchased both colors. I read the review on buying one size smaller. I really don't think that it is accurate, because if you do then you won't be able to wiggle your body in or out of the jumpsuit. Especially if you are thick and curvy? or average size and still have curves. I am 5'6 and 180lbs. and I have an XL it is perfect! with a little wiggle room. I read some of the comments about it was hard to get out of the jumper. I usually can wear a large as well and I decided to go up one size the length is good and the fit is true to size. I think the large would be a stuggle to get out of, and I did not want to go through the headache. Love both of them. happy I did not have to return!
