I am 5’7 and 155 lbs and ordred a 2x based on the size chart measurement. I’ve never worn this size before and was right between a 1x and 2x but figured better to be safe and go up. The 2x is a little loose but comfy. If i ordered more, i would order a 1x instead. I love the skirted legging style and find it very flattering. The fabric is not thick, more like silky pjs. Only reason i didnt give this 5 stars was because the waist band is twisting a bit. I hate when that happens.
