Polka-dot designs have long been a favourite of Princess Kate and before that, her late mother-in-law, Princess Diana. While the classic print is timeless, it’s all over the high street this season and one very affordable dress stands out – and it’s currently on sale for £37.50.

Back in 2022, Princess Kate turned heads in a chic white dress adorned with brown polka dots by Alessandra Rich. With long sleeves, a high neckline, softly puffed shoulders and a matching waist belt, the vintage-inspired dress gave a nod to 1980s style (and was reminiscent of a dress worn by the late Princess Diana). 

I’ve found a dress that gives a similar chic look but with a summer-ready spin. It would work for all sorts of occasions, including any races you might be attending. I’ve also curated a list of other picks from the high street. 

This elegant white polka-dot midi dress from Pretty Little Thing has a bateau neckline and a dropped waist, with an A-line skirt that falls to mid-calf. The bold black polka dots evoke vintage charm, while the clean tailoring and lightweight fabric keep it fresh and modern. This runs from sizes 4 to 16. 

This dress comes in a variety of colours, including a vibrant yellow—a standout hue that’s a major trend this season and seen on both Princess Kate and the Duchess of Edinburgh. Whether dressed up with heels and a clutch for a summer event or styled casually, it’s a versatile piece that channels classic femininity with a fashion-forward edge. 

Shoppers can currently get 25% off using the code PLT25, bringing the price down from £50 to £37.50. 

This strapless frock by British label Nobody’s Child, a brand previously seen on the Princess of Wales, exudes riviera glamour.

This elegant polka-dot maxi dress from French Connection has a timeless aesthetic, with a modern edge. Featuring a crisp white base with black polka-dots, it has a structured bodice and a voluminous A-line skirt, with removable spaghetti straps. The cinched waist enhances the shape, while side pockets add a practical, contemporary touch. Perfect for weddings, garden parties, or summer soirées, this dress is  available in UK sizes 10 to 18 but it’s selling fast.

This chiffon polka-dot dress features slightly larger black spots on a cream base, offering a bold, graphic twist on a timeless print.

This one comes in regular and petite lengths, in sizes 8 to 22.
