Thousands of racegoers were sent copies of the style guide ahead of the five-day event at Berkshire's famous racecourse, after the new dress code was announced in January.
The regulations include a no bare shoulder or thin straps policy and all racegoers must wear hats or headpieces.
Ladies' Day racegoers at Royal Ascot brave the rain, and the strict dress code.
BERKSHIRE, ENGLAND, UNITED KINGDOM (JUNE 21, 2012) (ITN) - The dress code might have been tightened, but that didn't stop a fabulous array of frocks and hats being worn to this year's Ladies' Day at Royal Ascot on Thursday (June 21).
A team of assistants was on hand to make sure the rules were adhered to by handing out pashmina-style shawls and fascinators.
In the royal enclosure the rules are even stricter - hats are compulsory, as fascinators are no longer deemed acceptable.
It is not just the women who have to dress to impress, men do too, and the style guide provides some guidance for them.
Men now have to wear a suit and tie in the grandstand, and black or grey morning dress in the royal enclosure.
In addition to the new dress-code guests on Thursday also had the weather to factor in. Thousands coped with showers on the third day of the races, teaming ponchos and wellies with their chic outfits.
Now in its 301st year, about 300,000 people are expected to attend Royal Ascot in 2012.
