Thursday night was The Red Dress Collection runway show. Which is an annual tradition at Mercedes-Benz Fashion Week at Bryant Park that usually kicks off Fall Fashion Week. The Heart Truth campaign is held to raise awareness about heart disease and women. So it's fashion for a cause, where each dress will be donated! Others who were involved in the runway show were Heidi Klum, Elisabeth Hasselbeck, Kim Kardashian, and Felicity Huffman just to name a few.
