Well...looking at your info, you could be Kairi from Kingdom Hearts 2.
I mean, you could make the dress a bit longer and put a jacket on over top I suppose...I mean, she doesn't JUST wear that all the time right? xD She's from the Video Game Kingdom Hearts. If you need any info about her just tell me~!
You could also be Misa Amane from Death Note II: The Last Name, which is the second live action Death Note movie. You could pull off a brown haired Amane, because her hair is dark brown/black in the movie. A simple dress would suffice.
Rio Kamichika from Durarara!! also comes to mind. Especially when she was younger, because she wore glasses then.
[Picture: http://sakecomsal.com.br/wp-content/uploads/2010/01/durarara1.jpg] The one on the left is her with glasses, whilst the one on the right is her without. Either one will do.
She has brown eyes, true. But you could still pull off a blue eyed Rio, that or you could get brown contacts... (If you were willing). Rio is probably the cheapest option, Kairi being the most expensive.
Well, I hope I helped!! Sorry if the links didn't work, you might have to copy & paste into the adress bar -_-
