One of the shades I love on my nails in winter is a deep dark purple!
It looks great on white skin ;) and is the perfect shade to lighten up big black coats / pullover.
Vendetta from Chanel Les Vernis is a great one. The shade is actually quite dark, so depending on whether you like it darker or more purpley, you can apply only one or the usual two layers.
I am wearing it this week with my new bracelet “Folk” from Caroline Najman, a French jewelry designer I am having a crush on.
