The Spice Girls are reportedly set to auction off some of their iconic outfits at a star-studded charity bash.

The Geri Halliwell's famous Union Jack dress is already on display at the Hard Rock Café in Las Vegas, she will be donating a number of basque-style dresses for the occasion.

Posh's PVC dresses, Mel B's leopard-print catsuits, Sporty's tracksuits and crop tops and Emma Bunton's babydoll shift dress will also be up for grabs.

Speaking about the charity auction, Victoria Beckham told the Mirror: "I've got all my costumes still. I can't wait for Harper to grow a little so she can have some.

"But the rest I'd like to put up for charity, I think it would be a fantastic thing to do."
