The Most Fabulous Hats From The Royal Ascot 2018

Fashion is one of the most important parts of the Royal Ascot, the posh 5-day horse racing event in England. In fact, the dress code is such a focal point of the festivities that there's an official style guide outlining all the do's and don't's of Ascot wear. Among the rules? "Hats should be worn." This tenet gives guests the opportunity to get creative with their attire. Royal events (like Prince Harry and Meghan Markle's wedding) are bound to yield the chicest or most outrageous headpieces, and the Royal Ascot is no exception. Here, we've rounded up the best hat moments from this year's installment of the high-society affair.
