I was scared by all the reviews that said these ran small so I ordered a medium (dark blue) and a large (light blue) and thought I would return the ones that didn't fit.  Here is the surprise - they both fit!!!  Medium of course a little tighter but Im keeping both pairs I like them that much!  I am 53 and weigh 125lbs.  These are so comfortable and I love that the leg tapers.  They are made of real denim and are soft and comfortable.  They are made well and just for fun might order other colors.  Hope this helps!
