Halloween costume ideas?

Im a teenage girl and i am overwhelmed with halloween ideas! Ok, so i was thinking about being a zombie princess, but i dont wanna make the mistake Caddy Heron made by dressing up at a scary ugly @$$ thing (mean girls scene btw) i sorta want to look, well hot but not slutty, so i guess u could say a good looking impressive costume that wont scare away the guys and parents!

So if i do the zombie princess ill try not to make my make up TOO scary. Ok, i got medium length hair (2 inches below the shoulder) and lightish, tannish colored skin (cool and warm colors work on me except yellow! -well i really havent tried yellow) so what princess should i be? It doesnt have to be disney, it could be from a video game, or just a famous female character like red riding hood.

So which princess? And any other costume ideas? I prefer it not to be scary but something good looking, or fun with makeup!
