While everyone is obviously already speculating on what Meghan Markle's dress will look like for her upcoming wedding to Prince Harry, there's also some buzz over what Kate Middleton will wear for the special day.
Deciding what to wear to a wedding is always tough — and it looks like Middleton will have an extra detail to potentially stress over: finding the right hat.
According to PureWow, it's royal protocol that all women must wear hats to official occasions. It's unclear whether this is an official rule or just a time-honored tradition, but we can probably expect to see Middleton donning some elegant headgear to the big event — just like she did during her sister Pippa Middleton's wedding back in May.
Middleton will have to keep a couple of rules in mind when picking out her hat. According to The Mirror, royal etiquette states that a hat worn to a wedding must be no larger than the hat of the mother of the bride. It also must not distract from the bride or obstruct the view of other guests.
Middleton has worn quite a few fashionable hats in the past, like this red Lock & Co. design adorned with maple leaves she wore for her trip to Canada in 2011.
She usually keeps her hat style on the subtle and small side, like this navy blue design with a bow embellishment by Rachel Trevor-Morgan.
Though she's also been known to give a more extravagant look from time-to-time, such as this light pink piece with a dramatic slant design by Jane Corbett.
Whether she opts for a subtle or over-the-top style for the wedding, we're sure she'll look as stunning as always.
