Who should I cosplay as?? Anime Cosplay?

Well I have never cosplayed before and heck it looks like fun to me. I just got home from my Second time of going to mega con and I saw the most perfect costume of Haru from The Cat Returns and last year I saw the most perfect costume of Princess tutu that almost had me crying because it was so perfect. I never really considered cosplaying because I wouldn't do it unless I could get every thing perfect. That's the way I am. I know that makes me sound rude but I would never cosplay unless I know I could pull it off! Plus for all you Anime fans don't take this the wrong way but y'all know your just a little strange and some people can point you out very quickly, but you show pride in that so that's good. I on the other hand do not look like any one who would show any interest in Anime I think that's due to the fact that I strongly disliked Anime up until summer of 2007 then I fell head over heals for it and now can name hundreds of Anime and manga yay. Back to the point I want to know what character I should cosplay as here are some details.

1. It can be from a game or Amime
2. I have dark brown hair that's in long layers I have long side banges and my over all hair length goes down to the middle of my chest.
3. Dark Chocolate eyes/ Brown eyes there kinda dark tho
4. My skin is kinda of a light olive/ I'm not that tan in fact I am some what pale.
5.I am 14 years old but by my next con I will be 15.
6. I am short =_= 4'11 …… But 5'0 with my converse on :) / I DORK
7. My Weight is 105 – 106 pounds/ not to bad I am some what thin/ so i would say average.
8. No tummy showing It creeps me out nothing that exposes my chest!!!!!
9. I am a girl, P.S I have clear skin in witch I take good care/ Although I dont think that matters
10. I have rectangular black framed glasses/ Although this character does not have to have them I don't wear them all the time. P.S The eye color does not have to be brown They have contax now for almost any color yay!
