I am usually a size small but went with the reviews and ordered a medium. They are of great quality but are a little high waisted for me.(not complete mom sweats) At 5'4 the length is perfect, while wearing shoes but a little long without. Happy to have purchased these, love the flare at the bottom just wish the waist was a little shorter.

P.S. Theses are very thick! I would say these are winter sweats only.
