Immediately recognisable for her madcap Philip Treacy hats, corsets, black bob and slash of red lipstick, Isabella Blow – eccentric fashion editor, stylist, talent spotter, champion of young designers and one-of-a-kind dresser – was a fashion force to be reckoned with. Six years after her untimely death, she has been the subject of several books (including Blow by Blow by her estranged husband Detmar Blow and Tom Sykes, and A Life in Fashion by Lauren Goldstein Crowe), as well as a play, Blow Me, which debuted in Miami earlier this year. This week, she is set to be the subject of Somerset House's latest exhibition, Isabella Blow: Fashion Galore!, which opens on Wednesday. Here's your need-to-know about a true fashion original.
