Authors from Charlotte Brontë to Suzanne Collins have imagined clothes for their characters that are almost as expressive as their wearers

The first clothes in western literature, Adam and Eve’s fig leaves, performed their essential fictional function in drawing attention to the protagonists’ moral failings.

Clothes in contemporary fiction seem to me to be an underused trope, perhaps because fast fashion has made individual garments less emblematic. When my own heroine Hannah is persuaded into a double murder plot by the rich Jinni on the London to Penzance train in The Golden Rule, it is no accident that her co-conspirator is wearing green.
