Playing the part of Andy Warhol's muse, party girl Edie Sedgewick, in the biopic flim 'Factory Girl' certainly put actress Sienna Miller in a revealing frame of mind. Attention seeking was Edie's trademark, so when Sienna turned up at the afterparty of the film's New York launch in what appeared to be Le Mystere control top panties with nothing over the top it was to be expected .

According to press reports Sienna has stocked up on Le Mystere the week earlier in Los Angeles after forgetting to pack her "knickers" for the trip. Perhaps she simply wanted to show off her new purchases to the Hotel Chelsea crowd? That and a guarantee of plenty of publicity for herself and the film. She succeeded on both counts.

What's concerning the fashion industry is the follow-the-leader syndrome that Sienna triggers. Let's face it, if she looked pretty silly in this outfit how tragic will the rest of the population appear?
