When it comes to nail polish, I adore holos and Color Club's Worth The Risque is the such a gorgeous one. It is a silver based polish with fine holo. It is a super easy formula to work with, and it is opaque in two coats. Worth The Risque is from the Femme Fatale collection in 2009, and along with it in that collection is another holo called Revvvolution. Revvvolution is a darker gray version of Worth the Risque that I really want to pick up!
For some reason my camera had a hard time picking up how gorgeous the holo really is. It is a little more true in the second photo.
