Ironing has become a pressing matter to some Americans. According to a 14-city survey by iron manufacturer Rowenta, 49 percent of U.S. residents like their jeans wrinkle-free; 37 percent prefer crisp, clean T-shirts; and 5 percent wouldn't be caught dead without starched socks. Forty-five percent of those surveyed would even head back home to change if they walked out the door in a wrinkled shirt. Let's hope these folks don't get too close to the iron: Respondents in 12 out of 14 cities say they press their clothes in the nude. Residents of Cleveland, Dallas, and Pittsburgh were most likely to iron two to three times a week. Those in Atlanta, Chicago, Denver, Los Angeles, Miami, New York, Phoenix, and San Francisco are steaming things up at least once a week. Those in Boston, Minneapolis, and Seattle aren't much interested in getting out the creases - they only iron on special occasions.
