Royal Ascot has become as much about what you wear as it is the races, so make sure you've brushed up on the rules before choosing your all-important outfit. Attended by royalty, celebrities and paparazzi, there's arguably nowhere more important to be sartorially savvy.
The strict dress code includes rules on hem lengths, shoulder straps and headpieces, and while everyone is encouraged to dress up for the occasion, each enclosure has slightly different rules.
Royal Enclosure dress code
- Dresses and skirts should be a modest length, falling no shorter than just above the knee.
- Dresses and tops should have straps of one inch or more.
- Strapless, off-the-shoulder, halterneck and spaghetti straps are not permitted.
- Dresses and tops with sheer straps and sleeves are also not permitted.
- Jackets and pashminas may be worn, but tops and dresses underneath should still comply with the dress code.
- Midriffs must be covered.
- Trouser suits are permitted but should be full-length and of matching material and colours.
