Lily James is the epitome of chic in a red gown at the star-studded BFI Luminous Gala in London

Lily James exuded glamour on Thursday evening as she led the stars at the BFI Luminous Gala in London’s Leicester Square.

The actress, 33, posed up a storm on The Londoner Hotel’s red carpet as she donned a gorgeous ruby red gown with a slinky satin material and figure-hugging design.

Featuring a halter-neckline and a chic train, the number accentuated her physique – while boasting an open-panelled back.

Lily’s auburn-hued tresses were gathered into a Hollywood-glam style bun, with two strands of hair left to frame her face.

She added a subtle palette of makeup for the appearance, lightly blushing her cheeks while adding a soft pink lip and black winged liner.

Posing over her shoulder on the blue carpet, the Mamma Mia star showed off the gorgeous gown’s design – with two thin straps gracing her mid-back, as the rest was bare.
