SIMI VALLEY – Nancy Reagan will open an exhibit Friday at the Ronald Reagan Presidential Library and Museum featuring red gowns worn in the White House by seven first ladies, including one gown worn by herself. It’s part of a national campaign against heart disease called The Heart Truth, and February is Heart Health Month. The first ladies who wore the gowns include Reagan and Laura Bush, Barbara Bush, Hillary Rodham Clinton, Rosalynn Carter, Betty Ford and Lady Bird Johnson. The Heart Truth campaign is sponsored by the National Heart, Lung and Blood Institute, which is part of the National Institutes of Health and the U.S. Department of Health and Human Services. Red dress fashion collections have been part of The Heart Truth campaign since 2003, and Laura Bush has been the national ambassador for the campaign since Valentine’s Day of that year. Some of the celebrities who have participated in shows for the campaign include Sheryl Crow, Lindsay Lohan, Vanessa Williams, Christie Brinkley, LeAnn Rimes and Eartha Kitt. The First Ladies Red Dress Collection debuted at the John F. Kennedy Center for the Performing Arts in 2005 when Laura Bush and Reagan first unveiled the exhibit. At the Reagan Library, the exhibit is scheduled to run through Mother’s Day, May 13. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
