I finally got my hands on the Katy Perry OPI collection, and the first polish I had to get on my nails is Teenage Dream. When I saw promo photos of this, I thought is would be really similar to OPI's Pink Before You Leap, but it is very, very different. The glitter in this is very flaky and chunky, in a good way, and is multicolored (as you can see in the photos below). It isn't too sheer either, 2 coats was plenty (although I did a 3rd just to make sure). I absolutely love it (and the name!).
