She rarely steps a foot wrong when it comes to her sartorial choices. 

And on Wednesday evening, Ellie Goulding, 30, landed herself at the top of the style stakes as she stepped out in a chic mesh mini dress for the Omega 'Lost In Space' anniversary party held at the Tate Modern in London. 

The singer's outfit of choice made for a leggy display and she looked sensational as she fronted the star-studded guest-list at the event.

Daring to bare: Ellie Goulding stepped out in a sexy semi-sheer mini dress for Omega's anniversary party held in London on Wednesday evening

Ellie's dress boasted an intricate design that dared to bare thanks to its mesh panels. 

A large semi-sheer section across her torso gave onlookers a glimpse at her killer abs, while a black panel that sat across her chest kept her assets covered in the stylish design. 

It's thigh-grazing hemline had all eyes on the Still Falling For You hit maker's lengthy pins - which she added height to with a pair of pointed quirky heels.

The starlet's trademark blond tresses were styled into tousled waves that tumbled past her shoulders and she was seen sporting one of Omega's luxury watches on her wrists. 

Her appearance at the bash in the capital comes after Ellie was seen teasing her fans with new music on social media.
