I've been wearing this Revlon Top Speed polish in Cloud almost all month. It's a beautiful and perfect lavender shade. It goes on really nicely and 2 coats is all you need since it's pretty opaque. The only downside to this polish is that it chips easily, after about 2 days there will be some minor chips and at 4 days you'll need to remove it b/c it'll be pretty badly chipped at that point. I can deal with the chipping though since it's such a pretty color. It reminds me of Essie's Lilacisim.
Have you tried any of the Top Speed nail colors? Which is your favorite polish at the moment?
