Gillian Anderson was the picture of elegance as she stepped out at the Olivier Awards in an eye-catching black dress.
The actress, a nominee at the ceremony, looked stunning in the fitted, floor-length gown, which had delicate thin shoulder straps and featured partially see-through sections.
A red bag added a pop of colour.

Darcey Bussell turned heads as she arrived at the Royal Albert Hall in a bold green column, which the Strictly judge teamed with simple jewellery.

Bussell’s fellow Strictly star Joanne Clifton was also among the style standouts.
The dancer wore a sparkly ice blue gown with a wrap over skirt and plunging neckline, with her blonde curls over one shoulder.
Beverley Knight also wore blue, but the singer opted for a more dramatic shade.
Her show-stopping dress had a black pattern and a piece of blue silk draped around the bodice and over the shoulder.

Former American Idol contestant Katharine McPhee added some glamour in a bright red, off the shoulder gown that matched the carpet outside the London venue.

Actress Nina Kristofferson also wore red – with a twist.
Her dress featured a pink ruffle which wound its way from her shoulder to the hem.

US actress Martha Plimpton chose a tux instead of a dress.
She looked fashion forward in the smart monochrome get up, with her blonde hair swept up off her face and a bright red lipstick completing the look.
