My friends and I described the college shower schedule/wardrobe.
Day 1: Clean. Hair down or pulled back in a cute pony tail, jeans and maybe a nicer T-shirt
Day 2: Slightly grungy. Hair definitely pulled back, Jeans may have given way to sweat pants and a grungier T.
Day 3: Grungy. Hair under a bandanna or cap (depending on your level of "Artsiness". PJs and or sweats. You swear you'll shower tonight but you just didn't have time before
Rinse, Repeat
