I’m 5’6 140 lbs & I usually wear a size XS-S in leggings. Size XS definitely didn’t fit me at al- they die not go past my butt. Size S was still very tight & short like high waters. Got a size M & liked how it fit and looked. Wished they were a little bit longer as I like my joggers to fit just a tad bit longer and just right fit at the ankles. Size L has the same size inseam as the M so kept the size M for a good fit- not too tight but not too loose. Felt just right when sitting down & the cuffed part doesn’t rid up at the bottom. Must buy!
