Beyonce Knowles took to the catwalk for Tom Ford on Sunday night (12.09.10).

The 29-year-old singer was among a number of stars to appear on the runway for the exclusive, invite-only show, with Julianne Moore, CHANEL Iman and Daphne Guinness also taking to the catwalk.

Speaking about the New York Fashion Week event afterwards, Beyonce confessed it had the "energy of a live show".

She told WWD: "It was so much fun. It felt like a performance. It had the energy of a live show. It's great to see people have fun in fashion."

Meanwhile, 70s-style fashion made a big comeback at New York Fashion Week, with Marc Jacobs debuting a collection heavy on dark colours in floaty fabrics, as well as a number of tailored jackets and wide-rimmed hats.

Halston also looked to the decade for inspiration, with bright colours and asymmetrical dresses making a big impact.

Sarah Jessica Parker - president of Halston - attended the event in a red creation from the label.

Among the designers still set to show are Vera Wang, Narciso Rodriguez, Michael Kors and Calvin Klein.
