20ltd.jpg20ltd-1.jpgWe've all experienced mortifying fashion moments such as being caught with the price label still stuck to the bottom of our Shoe Express bargains or sporting white underwear under a chic black number. However, none is more shameful then being caught out at a party in the same dress as somebody else. If that last doozy is a regular problem for you then 20ltd.com couldn't have arrived sooner.

This luxury e-store offers its wares with a twist - only 20 different things are available at any one time by some of the world's most talented designers. All are limited edition so once sold, they're gone. It goes without saying that this type of exclusivity is gonna cost ya, like this Derek Lam anorak for £990. But since there are only 20 in existence there's very little chance of someone wearing it next to you on the No.19 bus to work. The site launched at 7am today so act quick and be one of the first to check it out.
