The Princess of Wales made her first official debut when her engagement to Prince William was announced back in November 2010. Princess Kate stepped out in a breathtaking look, but it is not the first time we have seen her wear the sophisticated silhouette. The couple celebrated 14 years of marriage earlier this week and spent the day enjoying a trip in Scotland.

Princess Kate, 43, was a vision as she appeared in a royal blue dress, sweetly holding her husband-to-be's hand. Her breathtaking look not only accentuated her beauty but also her impeccable style, which has made her a global celebrity. This was the first of many iconic looks that were to follow, setting the bar incredibly high.

Her dress was designed by a British label, Issa London and was made from a soft silk-jersey wrap dress which featured soft pleats and a sleek V-neckline.

The Princess of Wales fell in love with the chic design and wore the very same style again, a year later. Prince William and Prince Kate toured Canada just months after their star-studded wedding, carrying out a series of public engagements.

The brunette beauty opted for the same style by Issa, in another regal colour - deep purple. She paired the design with a glittering maple leaf brooch which is worth £100,000.

Dark purple hues are often associated with the Royal Family and have dated back for centuries due to originating from Tyrian purple dye. The dye was originally made from the secretions of sea snails, which was extremely expensive in antiquity.

Kate’s dress was a huge hit with royal fans and after it was identified, it sold out within minutes. Buyers flocked from over 42 countries to get their hands on her look.

At the time, this was a huge boost for the brand, and it was reported at the time that they struggled to cope with the sudden, massive demand.

The intense demand following the royal announcement resulted in the company being unable to scale production to meet the surge, leading to financial difficulties and ultimately, the label's demise.
