It’s customary for women of the British royal family to wear a hat to official functions. As we recently discovered rules like "no public display of affection allowed" and "the correct way a lady should cross her legs" is just a few of rules that the Royals have to abide by. As we know, what the Queen says, is law.

These mandatory hats can either be elaborate, as Duchess of Cambridge, Kate Middleton, loves to wear or simple as Meghan Markle does.

The most-watched royal at the moment is the newly wedded Duchess of Sussex, Meghan Markle. She's been playing it safe by keeping her looks simple. She’s kept her outfits very plain since her new status. Admittedly this simple look is starting to bore me. 

Along with her outfits, her hats have been just as plain. Having said that she did step out of her comfort zone and wore a more create hat when she attended the Royal Ascot and more recently the centenary of the Royal Air Force.

Here’s a look at the hats Meghan wore over the past few months. From the simplest to the more adventurous.
