The style bindie is very new right now, and hopefully will take off very quickly. If you don't know what bindie is, then here goes: Boehemian and Indie mixed. A new hybrid of style that most older kids are into right now. The magazines are doing it, so why don't you?

[edit] Steps

Get a new hair color and get it cut. To play the part, you must first look the part. The bindie style mostly involves your face and hair. Color your hair to whatever you desire, but keep it short most of the time.
Wear the right clothes. Bohemian skirts are a cool idea, but as far as a shirt goes, thrown on a band tee shirt. Don't be afraid that you'll look too different from the rest, just be yourself, thats what being bindie is all about! Long broom stick skirts, Skinny jeans, striped shirts, lace, and bright colors are very nice together. For shoes: Vans, DC, Soda, and Rocket Dogs.
Wear the accessories. Hand warms of different colors are nice to have on hand, along with tons of bracelets. When you're bindie, there is no such thing as too much jewelery. Rubber bracelets, larger beaded bracelets, etc.
Put on the makeup. Different color eyeliners with neutral colors of eyeshadow go perfect together. Plus, a shinny pink lipstick or gloss is nice to have on hand, but never over do the lips. The eyes are the main part of the face when you're bindie.
Get to know what music you're into. Classic rock bands like led Zepplin, AC/DC, or CCR are really good bands to listen to. Bon Jovi is just amazing, so yea, listen to that to!

[edit] Tips

Don't be a poser! everyone will tell you that. You don't want to come off as being scene, or punk. Bindie is light and heavy, but keep it as light as possible!!!
You can still do all the sports you love. Being bindie should never interfere with your daily activities.
