Which cute iPhone 5 Case Looks Best?

My friend was looking at these cases and asked me which one I thought was best, to be honest, I'm even having a hard time choosing. I love the designs on all of them! Lol and the price is cheap, can't beat it! Please help me pick from the 13 designs (I'm going to get one too then I'll tell my friend which one I got lol)

I'm leaning towards #9, but #13's colors are just to die for! Very hard, which one of these would you guys get?

Go for number 13 as no.9 would become dirty very often.
