Every oversized (and outrageous) hat spotted at Royal Ascot 2018

Forget what the celebrities are wearing at Royal Ascot this year – all we really care about is the biggest and best hats.

Headwear must be worn at the historic racing event and so it goes without saying that racegoers invest a whole lot of time, effort and – no doubt – money in their hats. This year’s style guidebook (yes, there really are dress code rules) dictates that once again fascinators aren’t allowed, therefore big hats with big impact are the way to go.

Scroll through to see some of this year’s most show-stopping hats.
