The Spice Girls star said she has always taken a keen interest in fashion and found a way to make her compulsory school outfit look less horrific, reported Contactmusic.
"I created a fashion where you'd wear two pairs of socks - one pair on top of the other because it kind of bagged around the ankle. In my eyes, it changed how you looked in this horrific school uniform. It spread like wildfire," she said.
And the 39-year-old mother of four said she used a Gucci carrier bag to keep her books and belongings to school.
