Without ugliness, there is no beauty. Cultural commentator Stephen Bayley celebrates the power of imperfection.
Perfection is always tiresome. In human affairs, variety, risk, hazard and surprise are much more interesting than predictability and order. Consider the beauty spot, originally a minor superficial blemish that the fashion industry used to emphasise as a corrective to faces of bland symmetry. Marilyn Monroe had a famous one. This need to cultivate replicas of physical flaws is proof that, in matters of appearance, disturbance is often as valuable as calm and reassurance.
Today's equivalent of the beauty spot is the gap-tooth. Once, an ugly separation in the incisors needed urgent correction. Now it requires cultivation. Model Lara Stone has one, and Georgia May Jagger (the youngest daughter of Mick Jagger and Jerry Hall and now a sought-after model) used to put 50p pieces between her two front teeth during her school days, in the hope that her gap might get even wider. Other popular contemporary flaws include the model Arizona Muse's transgressive eyebrows, which remind you that if plucking eyebrows is one sort of vanity, then not plucking them is another.
Two of fashion's most familiar faces trade on jolie-laide imperfections and an ambivalent sexuality. The model Saskia de Brauw, whose style plays on ideas of masculinity, has the appearance of an unusually effeminate leader of a boyband. And Hanne Gaby Odiele, whose strangely distorted face stares at us from glossy front covers with the same chilling disapproval as a nun incarcerated in a forbidding convent in her native Belgium.
Beauty can be as boring as it is disturbing. The Prada AW12 video look-book has computer-generated models who are "genetically perfected clones". This flawless perfection terrifies even as it fascinates. Beyond fashion, imagine a world of uniformly beautiful people and things would be intolerable - a bus full of George Clooneys, or carpark packed with immaculate Ferrari 250 GTs. Meanwhile, Porsche's Panamera rejects all the ideas of form, function, elegance and simplicity advocated by Ferdinand Porsche himself. Instead, it is lardy and ill-proportioned. And it is a global bestseller.
