Whee I finally tried out OPI Teenage Dream from the Katy Perry collection and I have to say i LOVE it! It is pretty sheer, but I used 3 coats and it looks great. It dries really bumpy so a topcoat is needed. It's sooo sparkly though it's hard not to love it.
I decided to only use black shatter on half of the nail because Teenage Dream is so pretty I didn't want to cover it all up. I got the sideswipe idea from LOVE4NAILS on YouTube. She's able to do the sideswipe freehand, but for my mani I did use tape. I also added a line of silver glitter to add more sparkle!
