What to wear on the first week of school. I wanna change my look?

Ok. So. My friend usually helps me with this. We usually go shopping together and all. But she recently got out of the hospital, and her family went on vacation. I am getting a Hayley Williams haircut with reddish brownish auburn red highlights. and am losing weight. I wanna come back to school fresh, new, and totally different. Same personality though. I was planning on going surfer. Like those girls who model the clothes for Billabong and Roxy. The clothes they wear in the shoot. And I also wanna go punk. I am going to have a side bang punk hair cut. But I also have small beach waves. So I wanna be punkandscene/surfer/boho. so yeah. punk and scene are alike, and surfer and boho are alike. Help? Where should I shop and any other tips.
