Bunton, 37, was worried that people will make fun of their outfit, but admits that they got a great reaction, reports contactmusic.com.
"Me and Mel C went to a fancy dress party recently and I went as Baby Spice and she went as Sporty Spice. We got all the old dresses out and it was hilarious!" Bunton told Bang Showbiz.
"We thought about it and thought it would be fun but then when we were actually doing it we thought, 'What are we actually doing? We're going as ourselves!' But it actually worked out well. It was very funny and we took lots of pictures. It was really good fun," she added.
Spice Girls, formed in 1994, comprised of Melanie Brown, known as Mel B, Mel C, Bunton, Geri Halliwell and Victoria Beckham. The group disbanded in 2000 but reformed seven years later for a reunion tour. They last reunited for the 2012 London Olympics.
