Victoria Beckham We've always wondered what it would be like to step into Victoria Beckham's heels...

And wear her dresses and not breathe in her corsets.

Well, we now finally have the chance to do just that.

If some generous benefactor hands us a few mil, or we win the lottery, that is.

Because Posh is set to auction off some of the swanky Roberto Cavalli outfits she wore on the Spice Girls tour, says Entertainmentwise.

She's said to be putting up her fashion best for auction, in the hope that she'll raise £1m for a children's charity managed by her mum, Jackie.

 So, what can you get your hands on?

Up for auction is a Swarovski-covered minidress, reportedly worth around £250,000 and her gold leggings and corset which are set to sell for £30,000.

A spokesperson for Posh has said: "Victoria is putting together various ideas for the sale.

"She would consider offers from individuals - for the right price. It's time for any high-rollers out there to get their cheque books out."

Exactly where and when the auction is set for isn't known yet, but other reports say Posh has already had the garb flown to a storage facility in Blighty.
