Work: jeans and a shirt: washable (art supplies and body fluids may fly)
a handy sweatshirt (HVAC at school is random)
ugly and indestructable glasses (I want really ugly ones--horn rims a la 1965, but can't find them, so for now I have generic wire ugly sturdy ones)
shoes: must be soft: trying to be eye-to-eye with small people sometimes I kneel. My knees and ankles protest this behavior. *alas*

I wonder how long until black stirrup pants are fashionable again.
