The Heart Truth Red Dress Fashion Show 2013: Celebrities walk for a cause!

The Heart Truth’s annual Red Collection Fashion Show helped kick off New York Fashion Week tonight! Stars—including the Jenner clan (who presented a united fashion front in Badgley Mischka), fitness expert Jillian Michaels (in Cushnie et Ochs), Jamie Chung (in David Meister), and more—channeled their inner models to strut down the runway in New York’s Hammerstein Ballroom wearing vibrant red dresses by a variety of designers, combining fashion and famous faces to help raise awareness for heart disease. “Losing my mom because she wasn’t healthy really inspired me to live a healthy life,” two-time Red Dress Fashion Show model Minka Kelly (in Oscar de la Renta) told InStyle.com of the event, which was sponsored by the National Heart, Lung, and Blood Institute, Diet Coke, and WebMD. “It made sense to get involved and to inspire other women to take care of their hearts. This was a very lucky opportunity for me.” And there’s another reason to get involved, which Today anchor Savannah Guthrie (in Carolina Hererra) put best: “Who doesn’t dream of getting glammed up from time to time and having this experience?” Indeed!

"I got really lucky!" Kelly told us of wearing her crimson asymmetrical chiffon Oscar de la Renta gown for the fashion show. "When I got involved with this, it wasn’t about the dress, it was about the cause. I would wear a potato sack down the runway if I had to. I started doing cartwheels when I found out it was Oscar de la Renta!"

Kris Jenner, the Mother of TV Personalities, made her entrance to Beyonce's "Run the World (Girls)," wearing a Badgley Mischka design. After finishing her strut, she had her two youngest daughters, Kendall and Kylie Jenner, join her—also in Badgley Mischka—before heading off stage and giving her girls the spotlight.

Sisters Kendall and Kylie Jenner, joined forces and made their way down the runway together to the tune of Katy Perry's "California Girls" wearing fiery Badgley Mischka designs.

“This is so out of my comfort zone and the runway looks like it goes on forever!” said The Biggest Loser coach Jillian Michaels. What pushed her forward? Partly her Cushnie et Ochs dress, but mostly the cause. “It’s right in my wheelhouse. Heart disease is the number killer of women and 80% of those are preventable. So it’s worth it. I love fashion, just not when I’m the one on display!” The fitness fiend went on to walk the runway to the appropriate tune: Snoop Dogg’s “Sweat.”

Kelly Osbourne got ready in a hurry backstage, and clued us in to how she’s feeling. “I’m so scared!” she said. But her Zac Posen dress helped calm her down. “I don’t ever think of myself as a sexy person, but if I feel that way, it’s because of Zac Posen. He’s been so great to me, and so supportive of me, I feel like I’m forever indebted to him for that. I love him.”

Chung’s looks was all about the details—red nails, red lips, red shoes, and a sequin-covered David Meister floor-length gown the designer made within a week, inspired by the heart theme of The Heart Truth. “We had a fitting, and he suggested a cut that he already liked,” Chung explained. “But we did another V-line to accentuate the heart shape and really get creative with it.”

Pamella Roland dressed Gabby Douglas for the runway show, the same designer the gymnast turned to for her first Golden Globes appearance. “I love her style!” Douglas said of the designer. As for her strut down the runway—which she did to Alicia Keys’s “Girl on Fire,”—Douglas took her inspiration from Beyonce’s Super Bowl halftime show. “She is incredible, and she made it look so easy!”

“I’m in love with my dress,” the former gymnast and current NYU student said of her Reem Acra design. “I feel like I put on a wedding dress. If it was white, it would have been a wedding dress. It’s amazing. I’m a student so I had to do my fittings in between classes, and I’m just so honored to be wearing her.”

Kelly Clarkson's girl power hit "Stronger," played as statuesque Dallas star Brenda Strong sashayed down the runway in Marc Bouwer.
