ROYAL ASCOT

The finest thoroughbreds compete for millions of pounds in prize money at this eminent, 300-year-old race meeting in Berkshire. If you plan to base yourself in the Royal Enclosure, a space once exclusively reserved for the guests of King George III, strict dress codes apply: ladies should leave the fascinators, halter necks and spaghetti straps at home and opt for modest glamour, while gentlemen are expected to wear a black or grey morning suit.
