If you’ve ever wanted to dress like Victoria Beckham, you’re in luck – the style icon is about to auction off over 600 personal items directly from her own closet to help the charity Mothers2mothers.

The decision comes after Beckham visited the charity’s headquarters in South Africa earlier this February and was “moved” to get involved with their mission, training mothers with HIV on how to prevent their children from becoming infected with the disease while raising awareness to help keep women and families from the region healthy. The visit was sparked by an invitation from Anna Wintour, editor of Vogue magazine, to meet with Dr. Mitch Bessen, founder of Mothers2mothers. Beckham quickly accepted the offer.

“After spending just a few days with these remarkable women and learning more about the charity from Mitch and his lovely wife Annie Lennox, I wanted to do as much as I could,”said Beckham.

The charity sale will take place from August 20 to 25 with the help of The Outnet.com, an online fashion outlet retailer and auction house Christie’s which appraised the selected items that Beckham has decided to put up for bid. These include shoes, hats, handbags, jewelry, coats, ski-wear, and designer exclusives made just for Beckham.

“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,” recalled Beckham. “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. We approached The Outnet as they have an incredible global reputation and are the perfect partner for us to build awareness and raise as much money as possible for Mothers2mothers.”
