Usually a size XS but I sized down to XXS based on comments that these run large. XXS fits perfectly! Except for the length, way too long but fine with boots. Material seems stretchy thick and strong, and there is a zipper on each leg opening although I don’t see myself unzipping it. Love the material, comfort level and fit, just wish they made a shorter version. I don’t see myself wearing these to the gym, just out and about. And they feel kind of dressy, and probably could be except for the “alo” label by the back/side of the left knee.Alo Yoga,XXS,$138,5’3-5’4 5’3-5’4,Athleisure,Bottoms,Leggings,Size XXS All Reviews,Alo Yoga
