When I looked at these leggings straight out of the package, I was nervous.  They looked so small.  I thought they would be hard to put on and leave me with a muffin top.  I WAS WRONG!  These leggings were easy to put on and the waistband is so smooth and didn't cause a muffin top.  They are so comfortable.  I wore them on a very hot day and didn't suffer for it.  Highly recommend this brand and will definitely by this brand again.  I am five feet and three inches tall and approximately 135 lbs.  I mention that because these leggings are one size fits most.
