Rosamund Pike looks every inch the English rose in a sweet floral minidress as she giggles with her co-star David Oyelowo at premiere of A United Kingdom in New York

She recently gushed that her new film A United Kingdom is a 'wonderful love story'.

And it seems Rosamund Pike wanted to echo the theme of romance in her style on Monday night, donning a wonderfully whimsical outfit at the flick's world premiere in New York.

The actress, 38, looked every inch the English rose in the floral chiffon minidress as she posed with her beaming co-star David Oyelowo at The Paris Theatre.

Rosamund looked the height of irreverent glamour in the thigh-skimming ivory dress which featured cape-style trumpet sleeves.

Adding to the romantic look, the garment boasted a keyhole neckline adorned with red sequinned bows. 

The mother-of-two wore her ombre-hued hair scraped back into a tousled chignon and accentuated her striking features with a sweep of mascara and a rosy lipgloss.

Showcasing her enviably lean legs, the Gone Girl star added a dose of sparkle with some silver two-strap mules.

Having clearly bonded with co-star David during filming, the pair grinned at each other as they posed on the red carpet. 

Rosamund and David Oyelowo are the stars of A United Kingdom, which movingly re-creates the then-scandalous marriage between Prince Seretse Khama of Botswana and British typist grandmother Ruth Williams.

The couple caused an international stir when they married in the late 1940s.

In the inspirational film, Rosamund takes on the role of middle-class Ruth who falls for Seretse, an Oxford graduate and African king-in-waiting - played by David Oyelowo - after being introduced to him at a missionary society dance.

Their whirlwind romance and wedding wreaked havoc not only among their families, but at the highest political levels in Britain and southern Africa, where Seretse’s own Bechuanaland, now Botswana, was a longtime protectorate under British imperial rule.

Speaking of the movie on the Chris Evans Breakfast Show in November, Rosamund revealed: 'You see racism on both sides.

'It's this experience of a white woman craving to belong in the black world and being greeted with suspicion and hostility. They don't want a white woman to be the mother of their tribe.

'How is she going to understand the concerns of the women? How is she going to understand the concerns of the country? But she stuck it out.'

And speaking of Ruth's defiant will, the actress gushed: 'Sometimes you get these characters where you're like "God, if I had half of this woman's guts bravery and courage, I'd be such a better person"!

'It's a wonderful love story.'
