NEW YORK (CBS/AP) A catwalk of celebrities kicked off New York Fashion Week on Wednesday night, walking the runway at The Heart Truth's Red Dress Collection fashion show.

The event, where stars all wear red gowns from top designers, draws attention to a national awareness campaign about women and heart disease.

Denise Richards did the '70s look in a halter-top, empire-waist dress by Matthew Williamson, while Suzanne Somers went for a flared mini-dress with a jeweled waist by Ina Soltani.

Matthew McConaughey cheered on girlfriend Camila Alves in her sexy, tiny-strap asymmetrical gown by KaufmanFranco, snapping photos the whole show through. He later came backstage and the couple - who have two children together - posed together for pictures.

Susan Sarandon let her daughter, Eva Amurri, soak up the spotlight in her high-neck lace dress by Chris Benz. Sarandon, dressed in an unassuming pink polo shirt and hair pulled back, quietly took her front-row seat just a few minutes before the show began.

Taraji P. Henson strutted the catwalk in a Naeem Khan-designed beaded dress with a high slit, singing along to Michael Jackson's "The Way You Make Me Feel." Dita von Teese also participated, wearing a Zac Posen number that emphasized her hourglass shape.

Pop singer Natasha Bedingfield performed her song "Strip Me" at the end of her runway walk, wearing a deep V halter dress by Nicole Miller. TV personality Giuliana Rancic stood tall in a short red dress complete with sparkly Jimmy Choo heels.

Patti LaBelle hammed it up in her kimono-style dress by Zang Toi, and Linda Gray wore a Pamella Roland off-the-shoulder gown. Katrina Bowden went short in a flounce-front Oscar de la Renta.

Julianne Hough's red Swarovski dress played into the heart-health theme with its sweetheart neckline and her eye-catching necklace with crystals shaped into hearts.

Alberta Ferretti's eyelash pleat dress on "So You Think You Can Dance?" host Cat Deeley and Monique Lhuillier's rose-covered ballgown, modeled by actress Garcelle Beauvais, were both fashion standouts.

The Red Dress show has become an annual event in February at Mercedes-Benz Fashion Week, which officially kicks off Thursday for eight days of previews for the fall season. Some designers are further supporting the national heart disease campaign, sponsored by The National Heart, Lung and Blood Institute, by auctioning dresses through the Clothes Off Our Back website.
