Model-off-duty, be damned - Cara Delevingne was out and about in New York City yesterday in a slouchy look that we've come to expect more from the likes of Justin Bieber. The model was headed to a Kanye West concert, an event that somewhat explained her casual choices. If you're in love with the easy look, then you'll be happy to know it's a cinch to re-create: her sweatshirt is from Chloë Sevigny's latest Opening Ceremony collaboration, the jacket's from Rihanna's River Island foray, and her sunnies are from Australian brand Quay Eyeware. She finished the whole thing with Timberland boots. Whether Yeezus is on your agenda or you're just craving something comfortable, shop our picks here.
