Victoria Beckham is auctioning off the sleek and shiny costumes she sported on 2007′s Spice Girls Reunion Tour to raise $2 million for charity. The Roberto Cavalli-designed duds on the auction block include a micro-minidress encrusted with $500,000 worth of crystal diamonds, sparkling leggings, and a shocking gold corset V.B used to wow concert crowds on tour.

“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,” a rep for the pop singer says.

Details of the charity auction will be announced at a later date.
