Emily poses for a unusual campaign

Emily Ratajkowski has stripped down to her bra for a hot new campaign.

The 21-year-old matches her black lacy underwear with a pair of tight-fitting jeans for fashion label Rag & Bone‘s DIY Project.

The initiative sees models – who’ve previously included Miranda Kerr and Lily Aldridge – get given a bag of clothes and a camera so they can shoot an advert however they wish.

In one image, Emily shows off her tanned flesh while sitting casually against a wall and reveals her curves in a close-up image of her pert bottom.

Emily – who came to fame baring her breasts in Robin Thicke‘s controversial Blurred Lines video – also covers up her body in a couple of more low-key snaps.

She dons a buttoned-up shirt for a natural shot of herself gazing into the camera, in which she displays her flawless complexion by wearing minimal make-up.

The pretty Californian also sports a comfy-looking grey hoodie to pose by the water.

It seems Emily had a lot of fun creating the promotion.

‘It’s an exciting and crazy transition time,’ Emily tells Vogue.

‘I wanted to capture that by shooting basically in my empty apartment and around the city – it’s a fresh start.’
