Calling All Fashionistas!!!!!!!?

My preteen (Soon to be 12 years old) is coming out in a middle school/high school fashion show and we have no idea what to buy. We need outfit ideas. Through in some accessories too. Can you ladies help? I don't know if you need to know this, but she's 5'3'', 95lbs and brunette. She has to have a total of 6 outfits. She wants outfits that are preppy/girly, scene/urban, and something "Green" (as in something that promotes being environmentally friendly). Thanks for all your help!
