For female teens, I like to give them "bad makeup" like colours that don't really match, blusher is too strong, eyeliner is cray, wilder colours etc because in my head they've only just started experimenting with makeup. Also, I "dress-code" my teens as my high school did, including hair (unless your teen is a rebel/homeless/home-schooled). I give my teens friendship bracelets/coloured bracelets that don't match the rest of their attire. For male teens, I remove their watches, make them wear sneakers with everything, more loose clothing, basketball shorts with everything, or put on unnecessary sunglasses.
