The One Size fit was too large for me (slim build).  I'll now be skeptical of any other leggings that only offer One Size.  The lower cuff was too loose and kept bunching up above the kneecap.  I also wish the length was maybe 1 inch shorter.  The length is about at the middle of the knee cap or slightly above and the look just wasn't good on me.  I love the bright pink color!  The higher waistband was great and the material was soft and lightweight.  I wish I could have returned them, but that wasn't available.  I'll donate them to the local thrift store.
