I’ve worn a lot of vampy purples this month; here’s one more.  Essie Damsel in a Dress (Winter 2008) is a dark eggplant purple with fine silver shimmer:

Picture taken in natural light.  (Sorry about the bubbles!  That’s due to my topcoat.)  This applied well; two coats was opaque enough for me.  The slight shimmer gives the shade more depth; a sort of pearlized, glowy quality.  I paired this with Essie It’s Genius on my toes.
