The reviews for these sweats were all over the place so I am going to leave a good review and hopefully it helps some people with picking the right size. I am 150-155 pounds and I wear a size 10 in jeans and a size large in sweat pants and a size XL in pajamas, so I have my sizes figured out. Anytime I see a description saying something is oversized I buy a size down. I always order down with this specific brand unless the description says the fit is regular. I ordered a size medium and they fit great, it was a little tight pulling them over my butt, but they fit really good and they are not like balloons on my ankles. If you want a normal fit order down. I left pictures and hope they help.
