Ginger Spice , Geri Halliwell , wore a Union Jack dress . Spicemania was at its height in the UK and the Spice Girls had just cracked the US as well , reaching number 1 with their debut single and album . Halliwell was originally going to wear an all-black dress , but she thought it was too boring so her sister sewed on a Union Jack tea towel , with a ' peace ' sign on the back . The now iconic red , white and blue mini-dress was worn during the Spice Girls ' performance of their number one song " Who Do You Think You Are " . In 1998 she sold her dress in a charity auction to Hard Rock Cafe in Las Vegas for a record £ 41,320 , giving Halliwell the Guinness World Record for the most expensive piece of pop star clothing ever sold . This performance won the award for " BRITs Hits 30 – Best Live Performance at The BRIT Awards " at the 2010 BRIT Awards
