British designer Jenny Packham dresses the Duchess of Cambridge on a regular basis, but perhaps she wants to start attracting an edgier clientele. The collection in her runway show this Fashion Week was inspired by the femmes fatales of film noir; gowns were red, black, and gunmetal, with body-hugging silhouettes with wide sharp shoulders. Burlesque performer and tightlacer Dita Von Teese may have been recruited as an attendee in honor of the theme; she sat in the front row in cat-eye sunglasses and her usual Old Hollywood curls. This year’s Oscars nominations include a powerful group of leading ladies. Which celebs should don these gowns for the occasion and channel their inner temptress?
