Royal Ascot gets underway today with rules on what racegoers can wear at the festival much stricter than in previous years.
An official style guide has been produced for the very first time to help ensure no one strays too far from the expected high standards at the Berkshire racecourse.
Royal Ascot has strict guidelines for ladies in the Royal Enclosure, Grandstand and Silver Ring:
The advice for women in the Royal Enclosure is:
Dresses and skirts should be of modest length defined as falling just above the knee or longer
Dresses and tops should have straps of one inch or greater
Jackets and pashminas may be worn but dresses and tops underneath should still comply with the Royal Enclosure dress code
Trouser suits are welcome. They should be of full length and of matching material and colour
Hats should be worn; a headpiece which has a base of 4 inches (10cm) or more in diameter is acceptable as an alternative to a hat

Midriffs must be covered
Fascinators are no longer permitted; neither are headpieces which do not have a base covering a sufficient area of the head (4 inches / 10cm).
