It's back to school time with What Not to Wear. Erinn is a 16 year-old high school student about to enter her senior year. She's an A student – but when it comes to fashion she's scoring below average because of her mismatched socks and clashing colors. Stacy London and Clinton Kelly teach this teenager how to build a wardrobe that will take her through her senior year and onto college. Erinn needs to dump the too short shorts and skirts, and add a little bit more sophistication that reflects her hard work and accomplishments. As for make-up, Carmindy teaches Erinn how a little can go a long way – even in the every day setting of a high school classroom.
