NARS is bringing us some je ne sais quoi.

With vibrant bursts of coral, lilac and blue, François Nars' spring collection is based on Catherine Deneuve's Euro-chic style in the French classic "La Chamade." Released in 1968, the movie is based on the novel by French writer Françoise Sagan and tells the story of a beautiful "kept" socialite who has an affair with a working class love that brings exciting new world experiences to her otherwise sheltered life.

"I love Catherine's makeup in this movie," explains Nars. "It's very sophisticated and bourgeois in a Parisian '16th Arrondissement' way. She is the perfect reference for this collection, and apropos for spring - a time to embrace color and get noticed."

Long-time NARS collaborator Amber Valletta - who pulls off a flowing blonde blow out like no other - was tapped for the spring campaign, which was created and photographed by Francois Nars himself.

So why use Deneuve as a muse?

"She has a true sense of style, elegance and good education - but she has an edge. There is nothing obvious about her sexual image and power. Her seductive power is strong, but comes through without the typical corresponding aggression," says Nars.

While we can't wait to play with the sheer strawberry gloss and true blue shimmer eye pencil, we predict the Purple Rain polish is destined for wait lists; the intense violet shade rides the line between rock 'n roll style and royalty with a sophistication the French would be proud of.
