Every body is different, so you may have a different experience with these, but here is what I found.  I have a 38 waist; lots of garments sized that way fit me fine.  These were allegedly Extra-Large, 38-40.  Yet, they were tight around the waist and butt.  On my thighs, they also tended to ride up and leave a red mark where they settled.  If they fit properly, they would be wonderful--very soft, comfortable fabric, best design I have ever used for the private parts, very comfortable there. Very well made.  They just don't fit.  I'm going to try the next size, I like the other features so much.
