Inside Cara Delevingne's exclusive Nasty Gal party: Model celebrates with girlfriend Ashley Benson, Daisy Lowe, Nick Grimshaw and more

Model Cara Delevingne kicked off her Nasty Gal collaboration on Tuesday night with a star-studded party that saw guests including her girlfriend Ashley Benson, Daisy Lowe, Ella Eyre and Nick Grimshaw party into the early hours.

Delevingne arrived at the event hosted at The Box wearing a hounds tooth suit from her own collection, which featured a cropped jacket and wide leg pleated trousers.

Continuing with the cropped theme, she teamed the suit with a white top that revealed her midriff.

Delevingne's partner, Ashley Benson, also attended the event in a show of support for the actress and model. Benson, an actor who has starred in projects including Pretty Litle Liars and Spring Breakers, wore a corset top from Delevingne’s line.

Model Daisy Lowe also showed up to lend her support and was pictured having fun with BBC Radio 1’s Nick Grimshaw, who DJd at the event. Lowe kept things casual in a pair of high waisted black trousers and a white crop top.

Lowe and Grimshaw were seen grinning and smiling behind the DJ booth, where they posed for cameras and danced.

Kate Moss’ sister Lottie was also at the event, where she arrived wearing another piece from Delevingne’s collection - a black top with sheer panels.

The outfit bore a strong resemblance to one that model Tigerlily Taylor wore, however Taylor accessorised hers differently with a golden necklace.

Black sheer outfits were clearly the look of the night as singer Ella Eyre also chose an all-black look with a sheer sparkling top. She was joined by The Saturdays’ singer Vanessa White.

Other stars to attend included Louis Tomlinson’s younger sister Lottie, Lucy Watson and Phoebe Torrance.

Cara Delevingne’s Nasty Gal collaboration is currently available online and features a number of party pieces, including a high neck sequin mini dress, a series of faux leather blazer dresses and pearl-embellished tops and blouses.
