Organizers of the Royal Ascot race meeting say they're tightening their dress code by banning fascinators, small hats, from the royal enclosure. New rules put out by organizers Wednesday Jan 18 2012 are the latest in a series of changes and clarifications put out by those behind the super-elite horse racing event held each June. Other rules introduced or reinforced Wednesday include the requirement that women must wear hats and clarify that dresses must fall below the knee.(AP Photo/Alastair Grant, file)
