High-shine satin isn't very forgiving on the hips. But far and beyond these considerations, the likely reason for the dress's popularity is that it is by McQueen. In a celebrity culture obsessed by what's cool, McQueen is the ultimate label. No matter that the dress could easily be mistaken for something off the high street: the label gives it an edge in the eyes of the wearer. McQueen rather liked his position as cult designer to a select few. How he is reacting to such a motley crew of celebrities pitching up in his plum-coloured dress is anyone's guess. And how ironic that the designer who least craves star endorsement gets the most. Unlike most publicity-hungry designers, McQueen will not lend his clothes, willy-nilly, to any celebrity who asks. It is unlikely any of the women pictured here was given the dress for free, or even that their stylist borrowed it for the night. They would have had to pay the full £780 like the rest of us.
