Polka-dot prints have long been a signature favourite of the Duchess of Edinburgh—and we couldn’t get enough of the elegant Prada dress she wore in Bosnia on Thursday as part of her solo overseas trip. While the classic spotted pattern is undeniably timeless, it’s also having a major high-street moment this season, and we’ve found a near match at Debenhams for a fraction of the £3,500 price tag Sophie paid. 

The Duchess wore a designer piece crafted from lightweight fabric with a button-down front that’s effortlessly chic and versatile enough for year-round wear. The Duchess first debuted the look in December and has already repeated it several times, proving its timeless appeal.

The Daily Express has tracked down the exact designer dress the royal wore, along with a lookalike from a high-street favourite. And if you’re after short-sleeved options perfect for summer, don’t worry—we’ve got you covered.

The Duchess opted for a refined yet playful look in this navy and white polka dot midi dress by Prada. Crafted from lightweight nylon, the dress features a softly pleated skirt, a button-down front, and statement beige cuffs and a contrasting collar that adds a contemporary twist to the vintage-inspired print. Its tailored waist and fluid silhouette make it ideal for a polished daytime appearance.

Currently, only a size medium is left in stock, so act fast if you’re hoping to snap it up.
