There are so many rules to keep track of as a royal.
Many of which relate to fashion.
With Meghan Markle still fairly new to the royal family, we’ve been learning more and more about these fashion rules each week.
Coloured nail polish is a no-no, nude tights should be worn at all times, and wearing wedges around the Queen is very much frowned upon (she is apparently not a fan of the shoe).
But Princess Eugenie’s wedding on Friday has its very own set of royal fashion rules that guests and royal family members will be expected to strictly adhere to.
One – of course – involves millinery.
While royal protocol dictates that hats must always be worn by female members of the royal family to official events taking place before 6pm, at weddings held during the day, it is tradition for all female guests to don a hat for the occasion. And they must be worn inside the church.
Seeing as Princess Eugenie and Princess Beatrice have turned heads with their hat-game in the past – we expect to see some very striking headpieces on the day.
