For five days in June, 300,000 racegoers descend upon the small town of Ascot, to take a punt on the horses. The sport however is not what grabs attention but what's worn on attendees' heads.
As its name implies, Royal Ascot is a very high-class event. So it's of the utmost importance to dress correctly. And it should come as no surprise that £33 million ($51 million) was spent on fashion and beauty treatments alone, for Ascot Racecourse events, in 2013, according to Deloitte.
At most prestigious areas of Ascot racecourse, certain attire is mandatory. The most lavish: 'Royal Enclosure' will refuse entry to adults not wearing hats, or those wearing fascinators or headpieces less than 4 inches in diameter.
