In Washington, where professional women’s style statements are conservative, Hillary Clinton’s cleavage has suddenly burst into one of the hottest topics of the Democratic presidential race.The normally very conservative dresser’s slightly low neckline during a July 18 campaign debate on education mostly went unremarked at first, until Washington Post fashion writer Robin Givhan took notice and branded it a “small acknowledgment of sexuality and femininity.”Clinton wore “a rose-colored blazer over a black top. The neckline sat low on her chest and had a subtle V-shape. The cleavage registered after only a quick glance,” she wrote. The focus on Clinton’s bosom drew an explosion of “thousands of angry letters and calls” from readers.
