Ahhh, polka dots! They must be one of the most fun and flirty patterns of all time, and royals absolutely adore the wardrobe staple for a spring day.
It's easy to see why they love the humble polka dot so much, and it's not just because it elicits joy.
The polka dot is perfect for any event because it's so versatile and can work for formal and casual occasions.
It hardly offends fashion snobs, and it's also accessible for everyone who wants a bit of oomph to their outfits without accidentally creating a sartorial faux pas.
This European spring Crown Princess Mary totally embraced a Parisian chic polka dot look for a cross-country trip to France.
She attended the Generation Equality Forum opening ceremony in a regal black dress with white polka dots and a belted waist with gold buttons.
A few days later, Duchess Catherine stepped out at the Wimbledon Championships in a navy-blue polka dot midi skirt by Alessandra Rich.
The perfect piece was styled with a blue blazer and a white shirt, making it inarguably a perfect outfit for the tournament.
Kate's endorsement of the polka dot has been noted over the years as she's shown up to many events in the pattern, and she famously wore it during her 2013 pregnancy – which is perhaps one of her best maternity looks (see below for the breathtaking dress).
And Kate and Mary aren't the only royals who fly the polka dot flag for spring fashion lovers - there have been plenty of other aristocratic ladies who have totally wowed us.
See below for the most inspiring polka dot looks your wardrobe will beg you to replicate.
