My son is 5'4" and 120 lbs.  He wears a 29" waist & that's what I ordered for him.  The fit is perfect and they look great on him.  We always wash new clothes before wearing them, because the chemicals in them irritate his skin.  This is wear we discovered the problem.  We washed this pair of jeans in cold water and the patches came off.  OK, I'd read reviews stating as much, & had decided we'd just go without the patches if that happened.  But...  they left more than just the patches behind - lots of string and fuzz and junk - in my washer and dryer.  I can't afford to replace my laundry machines, so I'd best not ruin them by washing these jeans again.  So, my son will get to wear these once (now that they've been laundered), & then I will dispose of them.
