Cara Delevingne captures hipster chic for Saint Laurent’s grunge-inspired fall collection.

Cara Delevingne lets her hair down to capture the spirit of rock-star decadence for Saint Laurent’s grunge-influenced fall collection. The London “It” girl looks like she’s just survived a hard night of clubbing.

Delevingne, 20, comes from a long lineage of a long line of London debutantes, party boys and millionaires with tangential ties to British royalty. Sister Poppy, 23, is also a fashion model.

Cara is as well known for her party-girl reputation as she is for modeling. She pals around with Rihanna, Georgia May Jagger (Mick’s kid) and One Direction’s Harry Styles, according to London’sEvening Standard.

The willowy 5 ft. 9 in. tall model is becoming a fixture for Saint Laurent. The brand tapped last month to be the face of YSL beauty’s latest campaign.

In her latest shoot, she poses with musician Z. Cole Smith. Delevingne is often mentioned as the heir-apparent to Kate Moss, and she captures to a tee the heroin-chic look that catapulted Moss to fame in the 1990s.

Saint Laurent Creative Director Hedi Slimane set up the shoot and was behind the camera for the video shoot.
