I am 5'-4" about 110 pounds.  I like my clothes on the loose side and wear size 4 bottoms in most brands.  The size small knee pants fit me perfectly.  Not at all binding yet trim and neat looking.  The length is to the bottom if my kneecap.  I did not expect to like the polyester fabric (I am a big fan of cotton) but I do.  It is silky and flowy and drapes in a very flattering way.  In fact these drape so well the size mediums I bought still look okay even though they are too big.  The longer length with the sporty vent feels so good when I'm out walking.  I am so close to turning 60 let's just say I am.  I'm in good shape but my skin isn't what it used to be so I feel better with more coverage.  These pants cover yet are downright liberating with their lightweight comfort!!  Excellent for lounging around at home too.  And of course they do have pockets!!!  I'm back on Amazon to buy some more before they become unavailable.  I think the ones with accenting colors are probably quite spiffy but I go for the conservative look and buy the all black.  I'm am grateful to Champion for coming up with such a great style.
