Well it all really depends on your level of skill and what you're comfortable in, but the first character I thought upon seeing you (and it was probably your hair and nose ring! it's cute, btw) was Amane Misa from Death Note. She has a variety of outfits to chose from!
For some lesser known characters, you could probably pull of a pretty good Uo from Furuba. Maybe from back when she was a "yankee."

Lucia is cute, if you like Pichi Pichi Pitch!

If you like Naruto, you could get away with Ino, though your hair is a little short. Maybe Temari if you tried. (I also suggest Sakon, because he is awesome and your bangs remind me of him.)
You could try looking through a gallery of CLAMP art. They have so many characters I'm sure you could find someone!
I hope my ideas at least give you a push in the right direction! Good luck!
