Two decades ago, a fabulous fivesome joined together to create the pop culture juggernaut of the Spice Girls. Ever since, girl groups have been trying to rise to the heights that the Spice Girls once claimed. But their high only lasted a short two years: first Geri “Ginger” Halliwell bowed out of a concert tour in 1998, and then the remaining four — Victoria “Posh” Beckham, Emma “Baby” Bunton, Melanie “Scary” Brown and Melanie “Sporty” Chisholm — ended up choosing to go on an indefinite hiatus, which has turned into an unending break. While they all pursued solo paths, some in music (Halliwell and Mel B) and some in fashion (Beckham), they’ve popped up intermittently over the years to rekindle hope for a reunion.
