Singer Pharrell Williams has been causing quite a stir ever since he was spotted wearing Vivienne Westwood's Mountain hat to the Grammy's in January. After originally buying the hat from Vivienne's store World's End for £95, where it's still available in 12 colour-ways, he has decided to auction it on Ebay for charity following the media storm and interest from the public. So, if you have a spare $15,000 plus why not put in a bid for a good cause (thats at how much the bidding currently stands) or alternatively buy your own one for a much more affordable £95.
