Glamorous racegoers have arrived for the start of Royal Ascot as the five-day festival gets underway today. Jewel-coloured dresses, statement hats and dapper morning suits were all on display as revellers descended on the Berkshire racecourse this morning. Royal Ascot, the jewel in the crown of the UK racing calendar, starts today with the Queen Anne Stakes and will run until Ladies' Day on Friday. The Queen will officially mark the start of today's festivities with the royal carriage procession at around 2pm - but racegoers are wasting no time in getting the party started. Hat's off to them!

Visitors to the high-profile racing event this year also have a wider choice of garb, as organisers say they are free to choose a gender dress code they 'feel most comfortable' with. Under the changes, women will be allowed to dress like men and vice versa – as long as they stick to the rules. This year's Royal Enclosure dress code says 'Gentleman' must wear black or grey morning dress with a waist coat and tie. Girls' day out!

In previous years, it has insisted attendees cover their midriffs and avoid wearing fascinators and that still stands. While in previous years there has been no official style guide for the Windsor Enclosure, except to dress for a formal occasion, now female attendees are requested to wear fascinators, like those in the rest of the enclosures. Royal Ascot has put in place strict dress codes since the early 19th century . The race gathering's famously strict clothing rules hark back to sartorial trailblazer Beau Brummell, who dictated the dress for men in the Royal Enclosure at the turn of the 19th century and was fond of cleaning his shoes with champagne.
