The fashion designer and former Spice Girl, Victoria Beckham, has unveiled a new charitable project with the e-commerce site, TheOutnet.com.

Remember Beckham's fluorescent yellow Roberto Cavalli gown at the pre-World Cup party in 2006? Remember the white Dolce & Gabbana dress she wore to the 2003 MTV Video Music Awards? If you do, you're in for a treat, as they'll be up for grabs at the end of the month. 

Beckham first got the idea when she spent time with mothers2mothers, a charity that raises money to train and employ 'Mentor Mothers', South African women living with HIV, in order to educate them on how to prevent the transmission of HIV from mothers to babies as well as improve the health of women and their families.

Beckham then selected some 600 iconic pieces from her wardrobe, including 'Posh Spice' outfits that range from the early days of the Spice Girls through her courtship with footballer David Beckham, fashion party and runway show appearances and other major events. Pieces include dresses, coats, shoes, bags, hats, jewelry and even skiwear. The items were valued by Christie's, who will also host the sale, which runs from August 20 to 25 exclusively online at The Outnet, with all proceeds going to the charity.

"I laughed a lot when we were going through my wardrobe as the pieces hold so many happy memories for me, David and the children," added the 40-year-old star. "A lot of the clothes have been specially designed for me by the most talented designers and I've loved wearing them, however I now feel it's someone else's turn to enjoy them."

If you're interested, you can now register at The Outnet, ahead of the start of the sale. To add to the fun, ten of the most iconic pieces will also be on sale as part of a ‘Going, Going, Gone' reverse auction, where the starting price reduces by a fixed amount every five minutes.
