The most outrageous Royal Ascot hats ever

Royal Ascot is one of the highlights of the summer for the Queen and the Royal Family. Sadly, last year's installment was not open to the public due to the coronavirus pandemic, but this year races will be held from June 15 to 19.

While the Royal Family members who grace the races at one of the most prestigious social events of the summer sometimes steal the show, Royal Ascot and its strict dress code also sees some show-stopping accessories.

Since hats remain compulsory, British society ladies have celebrated the annual horse-racing event while showcasing their sense of style with some truly wild headpieces.

From royal baby-themed fascinators to elaborate, structural chapeaus, scroll through the gallery – or click through, if you're on desktop – for the most outrageous Ascot hats ever...
