Princess Kate defied expectations in corset dress during date day with Prince William

The British chill is in full swing meaning the scarfs, gloves and coats are out in action. So, we thought, who better to look to for some pre-emptive summer style inspiration than the Princess of Wales? Back in the early 2000s, the royal rocked many Y2K looks, leaving us with plenty to feast our eyes upon for year-round style guides.

Before she married into the royal family, Princess Kate was spotted at Wimbledon wearing one of her most ethereal looks to date. The royal-to-be donned a heavenly white corset dress featuring a boned peplum bodice, white pleating, spaghetti straps and a rich cream hue which accentuated her sun-kissed glow, no doubt courtesy of a beachside getaway with then-boyfriend Prince William.

Case in point would be back in 2005 when Prince William's wife-to-be stepped out in the Scottish town of St. Andrews prior to her graduation ceremony. The history of art student looked laid-back in some light-wash blue jeans featuring a low-slung silhouette, bell bottoms and an American It-girl feel.
