I am 145 pounds 5 foot 4. I bought a large in these leggings and they fit great. they are really comfortable. the fleece is thick and warm but they don't look bulky. the waist is high. maybe because I have a large. I hate tight stuff. they don't slide down or make weird rolls. the outside is very smooth. it won't pill but it can catch and cause strings to pull out. plus 12 bucks? I have 3 pairs now.
