Here in Portland, Oregon, I found out what most Web Camp 2000 campers like to wear and what their favorite stores are. Of course, not all girls love to wear nailpolish and spaghetti-strap shirts, and not all guys love to wear hats and a sleeveless shirts. Old Navy is also very popular, and Meier and Frank is the runner-up. Most girls like shortsleeve tops, and the boys like the exact same. Forget about sleeveless and spaghetti-straps.
Most girls prefer to wear their hair up in some style rather than down.
As for the boys, most of them seem to enjoy using hair gel. The majority of girls at camp like to wear nailpolish, but of course, you will always get some people who don't. Overall, girls shop at The Gap, buy shortsleeves, a few bottles of nailpolish, and a few hair accessories. I have made links to some of the most popular stores so you can shop online.
