Last night saw the royal premiere of Top Gun: Maverick in London, with Tom Cruise and Jennifer Connelly flying straight over from the Cannes film festival to present their latest movie.

Also in attendance were of course Prince William and Kate Middleton, who, after wowing us with her garden party outfit, stunned in her most daring look to date.

The Duchess of Cambridge opted for an off-the-shoulder black column dress with white trimming at the top, which perfectly matched husband William's tuxedo and shirt combo.

She wore her hair straight and down, accessorising with a pair of dangling diamond star earrings.

As royal protocol dictates demure looks, this is one of Kate's most daring outfits, likely deemed appropriate as it was an evening event.

Naturally, she sent searches for 'Roland Mouret black and white dress' soaring within minutes of being photographed at the premiere, but fans who'd like to copy her look will be disappointed to hear that the exact dress has now sold out.

A perfect affordable and versatile option.

However, I've found some great alternatives for you, including a past season gown from Roland Mouret that's remarkably similar, as well as some more affordable alternatives.
