Heart Truth Factoid #14:

Tonight is The Heart Truth's Red Dress Collection show, a buoyant (and stylish!) way to raise awareness for women's heart health.

But, nonetheless, 51.6% of American women are overweight, and 17.3% of women smoke, substantially increasing their heart disease risk.

So lose weight, stop smoking...and throw on a hot red dress to show your support (like of this great cause.)

Why are we promoting a happy heart? It's on trend of course!

This month, the National Heart, Lung, and Blood Institute (NHLBI) will host its annual star-studded Red Dress Collection runway show during New York Fashion Week. The Heart Truth initiative, as it is known, aims to inform women about the risk of heart disease.
