I got these in the large as I just had a baby and needed something easy to slip on. Ummm....definitely need to go up a size unless you like looking like a busted can of biscuits. I’m currently a size 12-14 and 5’8 165lbs but usually a size 8-10 155lbs. Good news is I can wear these after I lose my baby weight when I’m usually a medium so I guess I’ll keep them. Bad news is to get them on currently I’d have to lay on my bed high school style like I’m putting on a pair of low rise skinny jeans 2x two small.
