I have the same problem - check out lucy.com - (sorry, I don't know how to insert link..)this is a GREAT site! They have pants in 3 lengths and sporty hoodies, tops & flip flops,etc., too.
They are a bit pricey, but I really like their stuff. This site was around years ago, then they decided to stop selling online and you could only get stuf thru their store in NY. But, recently they reopened the site. I still have a tshirt, sox and pants from before & they are in great condition.
