Gerard Darel Charlotte Gainsbourg

BOBBING AROUND: Charlotte Gainsbourg rocks a new hairstyle — a shaggy bob — and a radiant smile in the fall campaign for Gerard Darel.

Breaking this week in Vogue Paris, the ads mark the 11th time the actress and singer has posed for the French contemporary label, back under the ownership of the founding Gerbi family.

Glen Luchford captured Gainsbourg wearing black trouser suits and animal print coats at the groovy Chatsworth, Calif., house that Frank Sinatra once called home. The mid-century stunner has also been used as a backdrop for episodes of “Mad Men” and “Californication.”

Gainsbourg cited a strong complicity with Danièle Darel, creative director of the firm. “So quite naturally, when she contacted me, explaining she was taking over the helm of her brand, I felt like being part of the adventure.”

Gainsbourg appeared in 10 consecutive Darel campaigns from 2003 to 2008.

The latest images appear in black-and-white and color and assert the concept that “without the personality of a woman, fashion would be nothing.”

The founding family, which had sold out to private equity firm Advent International in 2008, bought the struggling fashion firm out of receivership. It also comprises the Pablo brand.

The Gerbi family also controls trendy Paris retailer Merci, a rambling concept shop that opened in 2009 with a charitable mission.
