Celebrities have burst onto New York Fashion Week, donning couture red dresses made by top US designers and strutting the catwalk to raise money for heart disease.
Actresses, TV personalities, sports celebrities and musicians were dressed in custom-made red evening gowns to raise money to combat the No 1 killer of women in the United States.
The Red Dress Campaign is a charity gala that takes place every year during New York Fashion Week and organisers rely on the pulling power of popular names to rake in the cash.
US singer and rock guitarist Joan Jett, who lost her mother to congenital heart failure, said Thursday's event was very personal.
"You got no heart, you got no life, so I think it's important for women to recognise that," said Jett, dressed in a scarlet jumpsuit.
Singer and actor Anika Noni Rose, who appeared in the Hollywood film Dreamgirls, said New York comes alive during Fashion Week.
"I feel like you see more people on the streets dressed for Fashion Week, whether they're going to a show or not, because they know it's here. And it's pretty fantastic."
Rose said she was honoured to be taking to the runway in memory of a friend's mother who died of heart disease.
Singer Colbie Caillat wore a plunging gown by her red carpet favourite Nicole Miller.
"I'm excited. It's something girls always dream of doing and I'm also nervous because there's all these cameras," she said while having her hair primped for the runway.
One in four American women die of heart disease.
"The whole point is to bring awareness to women and it brought awareness to me. I had no idea that heart disease is the No 1 killer for women," Caillat said.
Actress Gina Torres was dressed in a bright-red Marchesa ballgown and had assistants scurrying behind, micro-managing the dozens of layers of tulle in her skirt.
"I feel incredible in it," she said. "It's like a fairy tale."
Ireland Baldwin, daughter of actors Alec Baldwin and Kim Basinger, looked stunning in a one-shoulder Donna Karan sheath dress showing off a tattoo on her arm.
"It's amazing, absolutely incredible. I mean it's so comfortable," she said. "I don't even feel like I'm wearing a dress, I feel I'm a mermaid or something."
New York Fashion Week kicks off the industry's autumn/winter 2014 season with a new look and 300 catwalk presentations before shows head to London, Paris and Milan.
It's dominated by big US designers led by Marc Jacobs, but emerging talent from Europe, Asia and, for the first time, Australia, will snip at the sidelines hoping for their big break.
