Fabric is comfortable. Size runs bigger. I wear a medium and would recommend a small. Rolled waist band to fit me. Cuffs are tight fitting. Very cozy fabric and warm.
My son bought me a pair of these for Christmas (at my request). I needed new loungewear/pj's and now that we're in more because of the pandemic, I figured, why not. I loved them so much I ordered two more pairs. They are not too hot and not too light. The patterns are great and they wash up wonderfully.
