Buy a designer camping bag by famous designers such as Louis Vuitton, Vera Bradley or other designers. You can find many designer luggage companies out there that you can buy from.
Bring clothing that have brand names on them. Buy clothing such as American Eagle Outfitters, Abercrombie and Fitch, and Hollister. Make sure people can see the brand of your clothing.
Take all your make up and accessories if you are a girl. Wear make up every day, do your nails and accessorize every outfit you wear. Match jewelry to your outfit and wear snazzy shoes.
Listen to cool music with your friends. Bring an iPod too so you can jam to your tunes when out and about. Choose hip and hot music so you will look cool to your classmates.
Pack your sun block and bug spray. Even if you are trying to get the perfect tan, you don't want to be running around with bug bites and a bad sun burn. It will not be a cool situation, so prepare yourself.
Bring cool magazines with you such as "Cosmo Girl", "Teen People" or "Teen Vogue". Read them with your friends and talk about all the celebrity gossip and events.
