If you're all about originality then those handcrafted fashion site are perfect!! I recommend Etsy.com it's a trusted site and stuff. I've ordered stuff from there and had no problems. check it out...
Or if there's something in particular you want, go to shopzilla.com. it will show you like a million places they sell that item so you can compare prices and stuff.
If you're lucky enough to have skirts then buy statement socks! yes I said socks. knee high, colorful one, any kind of sock you can think of so you can look like a little school girl (or boy?)
Buy stuff in different colors and styles so you can kind of change up everything and be uniform chic.
SHOOOOOES! They make like a million pairs of shoes in the world. Sneakers, flats, wedges, sandals! The possibilities are endless.
Hair!!! Your hairstyle will also make you stand out from the crowd. Try new stuff everyday.
