I'll tell you what I want, what I really, really want … and it's for Victoria Beckham to cosplay as her fashion-forward Spice Girls alter-ego, Posh Spice.

Well, Spice World got a taste of late-'90s nostalgia on Tuesday, when Beckham shared a photo of herself on the beach in a little black dress that is perhaps better suited for the club, à la Posh.

"Posh washed up on a Florida beach!" the fashion designer joked in her Instagram caption.

Clad in simple, strappy LBD, VB stood on her tippy-toes in the sand, one arm reaching upward dramatically while the other was adorned by an animated shovel and pail emoji and a peace sign emoji. Beckham accessorized with a neon green Bottega Veneta Padded Cassette bag and a pair of her signature aviator shades.

The Beckham clan appears to be soaking up the last of their summer on the beach. Just two days ago, VB shared a similar image of her and David Beckham's daughter, Harper, 10, enjoying the waves.

Counting down the days until Harper live-tweets her way through a Spice World screening.
