Princess Eugenie Embraces 1950s Chic Style For Date With Jack Brooksbank

Princess Eugenie was spotted leaving Lulu's private members club in Mayfair on Thursday night with her boyfriend Jack Brooksbank - and can we just take a moment to admire her dress choice.

Eugenie was channeling her inner 1950s movie star and styled out a black satin A-line dress cinched at the waist paired with a chic retro curl and a scarlet lip. This is officially her greatest look to date, and the big smiles suggest she knows it too.

The 24-year-old royal even got her shoes and accessories just right - note the green boxy clutch, statement rings and chunky peep-toe sandals.

Jack was also looking pretty dapper in a sharp suit, white shirt, blue flecked tie and some very jazzy (slightly Christmassy) socks.

Eugenie is currently living and working in New York but is taking a well deserved break from her busy role at Paddle8 auction house to be with her man. As for the long distance relationship? The couple, who have been dating since 2010, are making it look like a total breeze.

Clearly NYC - the most stylish city in the world - is rubbing off on Eugenie because she's definitely upped her fashion game. This 1950s look is super-chic and spot on for her shape. She should definitely wear a red lip colour every day of the week too.

Who said a real princess can't do trends?
