I got a $15 gift card recently from Sephora. I used it to buy one of their new polishes from their own Formula X line. It was hard to choose which one to get. Finally I made my choice on Crash, a cerulean blue glitter in a clear base.
This is one coat of Crash on top of Sally Hansen Xtreme Wear Pacific Blue. I love the contrast. Crash dries pretty gritty so top coat is pretty essential.
Is there any other Formula X polishes you'd recommend?
