If you’ve never heard of the Royal Ascot, now's the perfect time to brush up on the storied English tradition. The five-day horse race event is held northeast of London in Ascot, and is considered the Kentucky Derby’s chic British cousin—and everyone wants to be there (even Queen Elizabeth hasn’t missed it since 1945). And while the races may be the main event, the fashion is a close second. In true British form, hats take center sartorial stage.

To celebrate the 2015 Royal Ascot, we’re taking a look at some beyond-amazing fascinators from the soiree—including the playful umbrella-topped ones above—that prove the event is one of the most fun fashion days of the year.

Taking a cue from Queen Elizabeth's style M.O.—head-to-toe monochrome—this race-goer topped off her royal blue ensemble with a blue bow chapeau.

And who could forget the most famous attendee of them all, Queen Elizabeth II, who matched her fuchsia hat to her cheery overcoat.
