Are there any good stuff at Mint velvet clothing for plus size girls in Gothic style clothing?

I am in college now, and instead of bright clothes, I am keen on starting with Gothic clothing this session! I know not many people wall like it, but I seem to be fascinated with the Gothic style of clothing, and therefore, I am looking for some trendy yet affordable clothing lines that offer a variety of such clothes for someone my age, in a plus size. I have heard of mint velvet clothing from a guy friend, and I would like to know from somebody if they sell good stuff for young teenage girls of plus size as well! Can you guys please tell?
