What should I buy for my birthday?

So my birthday is July 5th and my dad told me I could use 200$ on anything online. Which really surprised me, I don't usually get presents like that. :P but he's working again so it's kind of understandable. Anyway, I've already bought tights (I usually wear skirts with tights), two shirts and a anew wallet. I have about 100$ or so left. what would you get? :) thanks!
