well i guess it depends on what kind of camp you are going to. If it is an outdoor camp, don't bother going shopping, except for if you are getting a pair of sweatpants or something. I mean, if you are going to be outdoors, if you go shopping and get a bunch of nice clothes, you will just look like some stuck up, girly girl. Just go with some comfy sweatpants (right now in the U.S. the capri rollup sweats are in style. And throw on a t-shirt
(not some raggedy old one though, just something comfortable and cute and colorful) Just keep it simple...in my opinion..but i don't really know cause I'm in the U.S. and things are always different here =)
Hope I helped,

P.S.I went to a camp earlier this year. It was an outdoor camp and i just wore jeans and a t-shirt with simple cami underneath. And just an FYI, no one wore anything fancy...just jeans and tshirts and sweatpants. =D
