Ruth Wilson channels sartorial chic in an electric blue pantsuit as she attends The Lost Daughter premiere at BFI London Film Festival

Ruth Wilson channeled sartorial chic in an electric blue pantsuit as she headed up The Lost Daughter premiere at the BFI London Film Festival on Wednesday. 

The actress and producer, 39, looked typically stylish in the bright ensemble by Alberta Ferretti, which boasted an off-the-shoulder blazer complete with halter neck and cami-style straps.

The auburn-haired beauty also modelled a pair of pressed slacks, while she stood tall in white boots.

Ruth complemented her stunning ensemble with a black purse, beaming as she was pictured at the event.

She styled her mahogany locks in subtle waves, while her glam makeup was completed with a slick of rose lipstick. 

The Luther actress oozed confidence as she strutted down the red carpet at the movie premiere.

Her outing comes as she hit up the True Things Premiere during the 65th BFI Film Festival at the Southbank on Sunday. 

The star was joined on the red carpet by fellow producers Tristian Goligher, Ben Jackson and Jude Law, as well as director Harry Wootliff.

True Things is a psychological drama film from a screenplay by Wootliff and Molly Davies.

The actress and the film's director, along with writer Davies, reshaped the original book's diary-like structure and created a screenplay which she described as a 'universal experience of infatuation'.

She told Daily Mail's Baz Bamigboye that she and Jude Law were working together on Eugene O'Neill's Anna Christie at the Donmar Warehouse more than a decade ago, when Law's production company was sent Davies's book — and Wilson was asked to have a read of it.

Wilson said what she loved about the book was that it felt 'incredibly feminine and truthful'.
