If there's one staple in Kate Middleton's royal wardrobe, it has to be the classic polka dot dress. Kate has been rocking polka dot dresses for over ten years, even sporting a budget-friendly £38 polka dot mini dress from Topshop in 2013 when pregnant with Prince George. Ever since, the Princess has regularly been seen rocking a chic polka dot dress for her Royal duties and special occasions, cementing it as a timeless style. So, we've found the best polka dot dresses top shop this season, inspired by Kate's own wardrobe.

Closer's pick of the best polka dot dresses, at a glance:
We personally love to turn to the Royals for style inspiration, whether it’s Megan Markle’s With Love, Meghan outfits or Kate’s recent outing in a checked Zara dress. But the outfits that live rent free in our head are without a doubt Kate’s polka dot dresses. Besides from the infamous Topshop dress of 2013, Kate’s other dresses tend to be by London-based Italian designer, Alessandra Rich. One of her most iconic dotty looks has to be the white and brown high neck midi dress she wore to Royal Ascot in 2022. The Princess of Wales wore a very similar Alessandra Rich design the following year during the Order Of The Garter Service at Windsor Castle.

While these two designer frocks are both white, Kate is also rather partial to a coloured polka dot dress. She wore two different blue styles to Wimbledon in 2022, both by Alessandra Rich. She styled both outfits with the same pair of slingback stiletto heels, for a sophisticated look.

It’s safe to say that Kate has given the polka dot dress a royal seal of approval. The good news is, the high street has no shortage of spotty designs this spring that can help you recreate her elegant style with ease without the designer price tag. We’ve tracked down the very best polka dot dresses that still emulate the same classy princess vibes, including the viral Nobody’s Child polka dot dressthat’s set to be a sell-out.
