Royal Ascot Ladies Day is one of the most glamorous occasions in the British social calendar and racegoers certainly did not disappoint as they kicked off the festivities this morning. Classic white sundresses, extravagant headpieces and very daring leg hemlines were all on show as hundreds of well-heeled revellers descended on the Berkshire racecourse for the third day of the meet. Among the early arrivals was a woman who brought an edgy twist to the dress code with a black long-sleeve dress with a revealing thigh-high slit, and another who turned heads in a neon pink hat covered in oversized pom poms. Others plumped for costume-inspired looks with a Queen of Hearts ensemble - complete with faux crown - and Union Jack dress both spotted in the crowds. Fortunately for revellers, yesterday's heavy rain has cleared and been replaced with glorious sunshine, which will surely encourage even more trackside fun and frolics. Best foot forward!

Visitors to the Royal and Queen Anne enclosures have to abide by a strict dress code, which does not allow bare midriffs or strapless dresses, but for guests in the Windsor and other enclosures the rules are more relaxed. The term Ladies Day was first used in 1823 when an anonymous poet described the Thursday of the annual meeting as 'Ladies’ Day … when the women, like angels, look sweetly divine.'
