ROYAL Ascot has made a number of stringent changes to its style guide ahead of its most popular race days, including banning off-the-shoulder shirts for women. 

Bardot necklines, which are named after the French actress Bridget Bardot, are no longer allowed within the Royal Enclosure at Ascot.
Also among the items that will not be permitted in the Royal Enclosure, are fascinators. 

Fascinators have grown to become a popular option for the races over the years, but this year the only headwear allowed will be hats or headpieces which have a solid base of four inches (10cm) or more in diameter. 

In 2017, following adjustments to the Royal Ascot style guide, it was decided that women would be allowed to wear jumpsuits for the first time. 

This year, jumpsuits will remain part of the permitted dress code, but they must be ankle-length. 

The same ‘not above the ankle’ rule applies to dresses as well. 

The full 2018 style guide is as follows:

LADIES

  • Dresses and skirts should be of modest length, 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 but should be of full length to the ankle and of matching material and colour.
  • Jumpsuits are welcome but should be of full length to the ankle, with regulations matching that for dresses.
  • Hats should be worn; however a headpiece with a solid base of 4in  is acceptable as an alternative to a hat.
  • Strapless, off-the-shoulder, halter-neck and spaghetti straps not permitted.
  • Midriffs must be covered.

MEN

  • A waistcoat and tie (no cravats)
  •  A black or grey top hat
  •  Back shoes with socks.
