If you’ve been paying attention to fashion.lately, you’ll know one thing for sure: polka dots are absolutely dominating the high street this spring-summer season. And if there’s one royal who loves a polka dot, it’s Princess Catherine. She’s been spotted countless times over the years wearing pretty polka dots, but arguably one ofher most popular looks was her Wimbledon dress which she wore in 2022.

The Princess of Wales stepped out in a navy polka dot design by Alessandra Rich at Wimbledon – a vintage-inspired look that instantly caught attention. While it’s believed her version was bespoke, anything similar from the label typically comes in well into the four-figure range, making it more of an investment than an everyday buy. And that’s where an affordable high-street piece comes in.

We spotted a gorgeous navy and white dress from Boden that taps into the same colour scheme and pattern as Princess Kate’s. A dress is an easy way to lean into the trend, without overthinking it. All you need to do it pop on one item and it does all of the hard work for you.

Cut in a flattering fit-and-flare silhouette, it’s designed to skim the waist and fall effortlessly, giving that easy, put-together feel without being restrictive. The navy base with classic white spots keeps things timeless, while the pussybow tie neckline adds that chic, slightly elevated finish. Though Princess Catherine’s Wimbledon dress doesn’t have a pussybow, it’s a style detail she has leaned heavily into this season.

The Boden number is the kind of dress that works for everything. Summer parties, weddings, race days, even just those moments when you want to feel a bit more put together without trying too hard. Available in sizes four to 22, it caters to a wide range of fits, and the structured shape means you don’t have to over-style it. Add a simple heel or even a ballet flat, and you’re done.

It still has that royal-inspired feel, but it feels actually wearable. If you’ve been searching for that one dress that feels current but won’t date by next season, this might just be it.
