British pop star Jessie J has gone one step further in her efforts to raise money for charity by auctioning off the bespoke catsuit she wore during the U.K.'s Comic Relief fundraiser.

The Price Tag hitmaker shaved her head on live Tv last Friday (15Mar13) as part of the star-studded telethon and donned a white and red polka dot catsuit made for her by British costume designer Wendy Benstead.

The sexy outfit raised a further $600 (£400) for the cause when bidding closed on auction website Sunday night (17Mar13).
