I need a great first day of school outfit?

I'm a teen, going into grade 8. Want a really cute outfit. I have casual shoes. Low top converse- gray and purple pairs. Gir (the alien dog) flats and black sparkly flats. Black, blue, purple, white flip flops. Cool white skate shoes with light green on them (Roxy McKennas and some DCs). I have dark wash shorts, light wash shorts, gray capris, darkwash jeans. It will be a little hot for jeans though. Oh and i have a cute red skirt and its like plaid but not.. Its Abbey Dawn. But i dont really wear skirts. Myschool has a dress code strict against tank tops and small straps and strapless tops. I like to wear any color. I like Aeropostale and Hollister for tops. I'm looking into getting new flats too and some other shoes. I like Aero, AE, Abercrombie and Hollister for hoodies and jackets. I can't go too expensive though. Please give some cute outfit suggestions <3 much appreciated! I want to have a great style in 8th grade!! Thanks!
