My son (7.5) is super-skinny and fairly tall. (He's about 4' 1" and maybe 45 pounds soaking wet). Even slims are too big in the waist. He doesn't like adjustable waist pants because the button digs into his hips. He doesn't like rivets. Anyone know where I can get comfortable pants for a super-skinny boy? He loves sweatpants, but I want something that looks not so ... well, sloppy. Help?!
