The words ‘girl power’ conjure vivid memories of short skirts and platform boots. But it wasn’t just about the look, it was about feminism.

The Spice Girls gave a generation their first glimpse of the power of friendship, of staying true to yourself, of sheer bloody-mindedness. And the girl power generation went on to kick-start a new conversation around gender equality.

We may have grown up asking What Would the Spice Girls Do?, but their particular brand of feminism is as relevant today as it was twenty years ago – we still need that fun and fearlessness, we still need accessible and all-embracing equality… we still need a zig-a-zig-ah.
