We鈥檝e wanted to raid Victoria Beckham鈥檚 closet from the first time we saw her strike a pose as Posh in her signature black strapless dress (we knew that any gal rocking a long bob and a nude lip during during that grungy and glittery decade had to be on the cusp of something sartorially amazing). And today our tween dream has finally come true with the news that the designer will be selling more than 600 items from her personal collection, spanning from her time as a Spice Girl through now on The Outnet.

鈥淓very single piece that I have put in to be sold brought back a lot of memories, a lot of really, really happy memories of myself and David, of myself and the children, of different events that I鈥檝e been to,鈥 Victoria said in a video promoting the exclusive online sale, which takes place from August 20-25. 鈥淎 lot of these pieces have been made specially for me by the designers鈥 these haven鈥檛 all been bought off of the shelf.鈥

Besides a slew of chic off-the-red-carpet looks up for sale, Victoria has hand-picked her 10 most iconic looks for a special 鈥淕oing, Going, Gone鈥 reverse auction, during which the price for each garment will gradually drop. Among those one-of-a-kinds include the white lace-up Dolce & Gabbana dress worn at the 2003 MTV Video Music Awards and the neon yellow Roberto Cavalli gown Victoria was snapped shaking it in at a pre-World Cup party in 鈥06 鈥 both throwback glamour silhouettes which we鈥檇 die to wear (and fit into) even today. You can register for the sale online now 鈥 proceeds will go to mothers2mothers, a charity that works to eliminate paediatric AIDS.

鈥淧eople have asked, aren鈥檛 I keeping all of these pieces for Harper? I鈥檓 keeping a few pieces, but, for me, it was more important to raise money for this charity,鈥 Victoria said. 鈥淎s a woman, we have a responsibility to really help and support other women.鈥 We鈥檙e happy to hear after all these years that you definitely cannot take the 鈥済irl power鈥 out of the girl.
