And it seems a little strict...


It was announced this week that Prince Harry and Meghan Markle are officially engaged, with the highly-anticipated news confirmed by the Prince of Wales in a brief statement issued by Clarence House.

The royal couple have since made their first official appearance at Kensington Palace where they posed for photos in the sunken garden and then sat down for a televised interview with BBC's Mishal Husain.

Now that we know the special meaning behind Meghan Markle's engagement ring and the date of the nuptials has been set for Spring 2018, speculation is mounting around what we can expect from a Prince Harry and Meghan Markle wedding.

Who will Harry choose as his best man? Who will Meghan select as her Maid of honour? Will Meghan choose an English or a Canadian designer to create her dress? And will we get a day off work for the royal wedding?

A lot of the focus has surrounded Kate Middleton, whether she'll be a bridesmaid and if there are any rules she will have to stick to for the big day.

Well as it turns out – yes, there is one big rule that the Duchess of Cambridge must abide by on Prince Harry and Meghan's big day – but it's not what we expected.

As a royal woman, Kate is expected to always wear a hat for formal occasions – and this royal wedding is no exception.

While we all browse hats and fascinators as part of our wedding shopping prep, it is not an option for the Duchess, but a strict rule that she has to follow.

Good thing Kate looks great in hats!
