MORBIHAN, France, Aug. 2 (UPI) -- Waitresses depending on tips for much of their income can dress for success by wearing red, which brings higher tips from male customers, French scientists say.
Nicolas Gueguen, a psychologist at the University of South Brittany, and his colleague Celine Jacob found not only that male patrons gave higher tips than female patrons in general, but that men gave between 14.6 percent and 26.1 percent more to waitresses wearing red, while color had no effect on female patrons' tipping behavior at all.
