It could be time to don your best Vanilla Ice fancy dress, because one of London's hottest dance festivals has announced a 1990s theme this year.

LED Festival will arrive in London's Victoria Park on August 28th 2010, bringing along acts such as Goldfrapp, Calvin Harris and Friendly Fires for revellers to enjoy.

However, a highlight is sure to be the fact that Pump Up the Volume is hosting its own arena, reports.

It will take partygoers right back to the '90s with hits from the likes of En Vogue, Jazzy Jeff, Vanilla Ice and TLC and to celebrate, organisers have announced a fancy dress competition.

"Those with the best outfits will win an upgrade for them and their mates into the exclusive Pump Up the Volume VIP Arena … make sure your jeans are baggy, your tops are cropped and t-shirts carry a smile," the website states.

While a rapper costume may be ideal if you're a guy, girls could opt for sexy fancy dress in the form of a Neon Groove costume reminiscent of Dee-Lite's Groove is in the Heart.

Don't forget to take a whistle to bring back memories of all those raves!
