There's a photograph of Vivienne Westwood above that I absolutely love. Shot by Jillian Edelstein, it shows the late fashion designer in close-up: flame-orange hair wild against a warm brown background, two small silver horns tucked into her curls, her expression somewhere between mischief and defiance.
It's funny, strange and tells you more about her in a single frame than most interviews managed in an hour. It's also, technically speaking, a celebrity portrait, but it has little in common with what that phrase usually implies.
