The Spice Girl, 50, said: "It is now the moment to unleash my '90s leopard catsuit back into the wild for the world to admire. What memories. What a time. What an outfit.
"Perhaps one of the most iconic Spice performances with my gorgeous girls and best friends at the peak of the '90s at the Brit Awards. A glorious moment when we came home to celebrate a rollercoaster seven months after exploding from unknowns in July 1996 to feeling like we had conquered the world. It was all a crazy '90s whirlwind but, in my leopard print, I knew I could take on anything.
