[ Fashion & Accessories ] Open Question : Where can I buy designer pencil / makeup bags?

I'm 14 and I'm going to be a freshman this year. Last year I used a Juicy Couture pencil bag but this year I don't want to use juicy. I also use makeup bags as pencil bags sometimes too. I hav seen the Coach makeup bags but to me they're kinda small. So does anyone know where I can get designer pencil bags? I already know clinique has good makeup bags for pencil bags. But I'm looking for brands like Louis Vuitton, Burberry, etc brands. Not too big not too small. Price is not an issue. And please don't say I don't need a designer pencil bags. I know I don't need one but I want one. Thanks :)
