The premiere fan-managed social network for Josh!
Strappy monochrome heels added to an already distinctive look, as did her only visible accessory -a striking silver clutch bag, held in her right hand.
Liberally applied red lipstick gave her ensemble an extra splash of colour, while her long willowy locks were loosely tied in a conventional ponytail.

The actor added to his look with a smart mid-length jacket, while suede boots rounded things off as they oined a guest list that also included Daisy Lowe and Katherine Jenkins.
The couple, who welcomed their first child in 2015, have kept tight-lipped about their pregnancy, but Tamsin appeared to confirm she was expecting at the Vanity Fair Oscars after-party in February, as she poked fun at her pregnancy diet with fellow guests.
