Before I did this activity, I'd already done some PQA and a story using clothing words. I'll put those up eventually.
Materials: lots of clothes, the weirder the better. Ask your drama department to borrow some if you can't gather them on your own, or ask the kids for volunteers (don't require it especially if you have a poorer population).
A small whiteboard for each judge is also helpful but you can use paper.
Roles: stylists, models, judges. Photographers optional.
Setup: Set up the desks so there's a "runway" for models to walk. Put all the clothes and accessories in one place. Put useful vocab up on the board, including colors and patterns as well as clothing terms. Have water handy because you're going to be talking a lot.
