No fashion roadkill here!

Celebrities like AnnaSophia Robb, Lindsey Vonn, and NeNe Leakes masterfully walked the catwalk in vibrant red gowns on Thursday, Feb. 6, for the annual Heart Truth Red Dress Collection during Mercedes-Benz Fashion Week in New York City.

Although the fashion show, which promotes women's health awareness, was a departure from the leading ladies' day jobs, first-timer Colbie Caillat, wearing Nicole Miller, said she felt prepared for the catwalk. "It's something girls always picture themselves doing, and you always practice whenever you're strutting your stuff down any street," the "Bubbly" singer, 28, told Us Weekly. "So to get to do it tonight in front of all of these people while bringing awareness to heart disease and walking with all of these amazing women is really special."

One upside of being sidelined from Sochi because of an injury: Walking in the Heart Truth Red Dress show. "Right now I feel great," gold medalist skier Vonn, 29, in Cynthia Rowley (and crutches!), told Us. "This is an amazing event for an important cause with amazing people so I'm just grateful to be here."

The Carrie Diaries star Robb, 20, wore a fire-engine red and navy Alice + Olivia gown. "Looking forward to "GoRedForWomen & @TheHeartTruth Red Dress Collection tonight!" she tweeted before the event. "Can't wait 2 wear my gorgeous @aliceandolivia dress! #NYFW"

"Honey, I'm excited!" the Real Housewives of Atlanta star Leakes, 46, told Us before the show. "I get to wear Dolce & Gabbana so I'm really excited about that!"
