Long before Princess Catherine became synonymous with elegant tailoring, sweeping midi dresses and timeless investment pieces, there was one designer outfit that defined an entire chapter of royal fashion
When Prince William announced his engagement to the then-Catherine Middleton on November 16, 2010. The future Princess of Wales stepped in front of the cameras at St James’s Palace wearing what would become one of the most memorable dresses in modern royal history
Designed by London-based label Issa and its founder, Daniella Helayel, the sapphire-blue silk jersey wrap dress instantly captivated royal fans

Featuring a flattering crossover neckline, softly gathered waist, pleated detailing and an above-the-knee hemline, it perfectly embodied the polished yet contemporary style that defined the early 2010s
Retailing for around £430, the dress became one of the biggest examples of the so-called “Kate effect”, reportedly selling out in more than 40 countries after the engagement photocall as shoppers rushed to recreate her elegant look
It wasn’t the last time Kate reached for the now-iconic design, either
Clearly fond of the flattering wrap silhouette, the Princess went on to wear the same Issa dress in several different colourways

Together, the Middleton sisters helped transform the wrap dress into one of the most recognisable fashion moments of the decade, with demand becoming so extraordinary that it cemented its place in royal style history
Yet while the dress perfectly captured the mood of the early 2010s, it also serves as a reminder of just how dramatically both women’s wardrobes have evolved over the past decade
Today, it’s difficult to imagine either Princess Catherine or Pippa reaching for a hemline that sits several inches above the knee

Instead, both have embraced sophisticated midi and maxi-length silhouettes that have become hallmarks of their polished, contemporary style
For Catherine, that evolution has mirrored her changing role within the Royal Family. As Princess of Wales and future Queen, she has increasingly centred her wardrobe on beautifully tailored coat dresses, elegant evening gowns and classic investment pieces designed to transcend seasonal trends
Pippa has undergone a similar style transformation, favouring refined occasionwear and timeless separates while maintaining the understated elegance that has long defined her personal style
