The tall urbane scrubs are the best fitting scrub pants I have found so far.  I'm 5'8" and wear a size 8 pants.  These are long enough to not run into the problem of deciding to either have the bottom of scrubs halfway up your calves when you pull the waist up, or have the crotch down between your knees when you try to let them ride lower. The drawstring avoids the problem of having the waist band reveal more than you want when bending over like an elastic waistband would.
