The phrase "Dress For Success" comes from John T. Malloy's 1970s books Dress For Success
and its follow up Women's Dress for Success
. These books started off the idea that working men and women should dress in a professional manner so as to be taken seriously. John T. Malloy was America's premier scientific image consultant and his books kick-started the image consulting industry and encouraged corporate women to wear for work full-jacketed sober suits.
