She paired the sequined gown with pale pink open-back heels, and opted to wear her brunette locks tied back in a loose ponytail. 

And, never one to forgo the glamour, the Doctor Who star donned a flawless face of makeup finished off with a dusty rose lip. 

Eleanor, 27, put on a leggy display in an elegant black skirt, which featured a daring thigh-split on her right side.

The actress, who is also known for her role as Princess Isabelle in Jack the Giant Slayer, paired her midi skirt with a high-neck, capped sleeve blouse. 

And the beauty opted for grey open toe, knee high stiletto heeled boots for the hotly-anticipated conclusion of the polo tournament. 

The Angus, Thongs and Perfect Snogging star wore her auburn locks in loose waves, tucked back behind her ears, and completed her look with delicate silver hoop earrings.

Eleanor was joined at the event by television presenter Maya Jama, who wore a dark grey, flared leather skirt and a simple white blouse.
