Websites that sell gothic victorian clothes/dresses in extra small sizes?

I like clothes that are gothic/victorian style, and my 15th birthday is coming up soon. My mother said that i can buy a dress from a website if i can find any. I did find alot, and the dresses and other things werent expensive and they were really pretty, but there is one problem: I am kind of short (4'10) and the smallest size that those sites had in extra small was 32-34 inches in the bust size. and I have a 30 inch bust. Can anyone help me and give me some sites that have clothing with sizes that would be able to fit me around the bust? I cant make my own dress since my mother wont let me use the sewing machine (i have bad eye sight, so she is afraid that i will hurt myself) and we dont have hot topic where i live (norway). I will appreciate the help :D
