I ordered a XL it fit perfect! Love the feel and the Savage Fenty band! Very comfortable.
I am 5'9 185lbs, I purchased the large. theses fit perfect for me. If you like your leggings snatched tight then I would go with med. but the large fit perfect and super comfortable.
I'm 160lb . I got a medium and It fits comfortably. Because of my stomach getting bigger I got a medium I was skeptical about getting a small . The medium is loose around crotch area but I know the small would have been too right around waist . I prefer a tighter fit but I love that this is just so comfortable and the fabric is super soft. With the matching top this duo give me life.
