Posh rubbed shoulders with the likes of British Vogue editor Alexandra Shulman (above) and US Vogue Editor in Chief Anna Wintour at J Crew x Vogue Cocktails event at Winfield House on Tuesday night.
She looked elegant and chic in a drop waist ruched shift dress from her own Autumn/Winter 2014 ready-to-wear collection, which she paired with a slathering of fake tan and sleek black stilettos.
The mum-of-four is still celebrating showing her S/S 15 collection at New York Fashion Week to rave reviews and, back in London, has been overseeing the work on her new flagship store on Dover Street.
Other stars at the bash included Burberry's main man Christopher Bailey, model Jourdan Dunn, singer Ellie Goulding, Bradley Cooper's girl Suki Waterhouse and model Cara Delevingne.
Cara looked incredible in an electric-blue velvet jacket - and not a lot else. She donned a gorgeous delicate pair of ankle-strap wedges, her hair was in a chic relaxed updo, and she finished with a pop of raspberry lipstick. Perfection.
Ellie Goulding, meanwhile, ramped up the sex factor in a backless halterneck bodysuit worn under leather trousers with cool ankle boots to finish.
