Royal fans are used to seeing the ever-resplendent Princess of Wales looking nothing short of refinedly beautiful. The wife of Prince William never puts a toe out of line when it comes to her incredible royal wardrobe.

From tailored suits and Breton-striped tops to A-line dresses, tweed separates, and the mighty coat dress, Kate's timeless style is widely admired due to its classic stance.

Kate is known for her classic and timeless take on fashion

The mother of Prince George, Princess Charlotte, and Prince Louis has always adhered to the royal style handbook, which cites a myriad of mindful choices - from reserving the colour black for mourning only, to wearing hemlines past the knee. Royal ladies are the epitome of decorum and grace, and these rules command fashion respect in formal settings.

Kate's pre-royal wardrobe

Before Kate officially married Prince William in 2011, her wardrobe choices were far more relaxed than they are today. From her 'naked' dress she wore on the runway at St. Andrew's University to her disco girl hotpants alongside little sister Pippa at a rollerskate disco, Kate's style was more playful.

A great example of this is back in 2006. Then known as Catherine, the brunette beauty donned this pretty tonal halterneck sundress.

Cheering on her future husband, Prince William, at Tidworth Polo Club, Kate's dress boasted a low neckline and was totally backless, secured by tied straps that finished at the neck.

This type of dress was often embraced in the 50s by pin-up stars such as Marilyn Monroe. Although the style was flirty, fun, and stylish, the fluid shape and shoulder-baring style isn't the cut she would embrace today as a senior royal; it would be best suited to an off-duty, holiday environment.

Also in 2006, Kate made a quiet appearance at the Chakravarty Cup charity polo match at Ham Polo Club.

The royal, who was in her early twenties at the time, stole the show in a back-baring dress once again. This time, she chose a tomato red number that was adorned with pretty polka dots. Accessorising to perfection, the future Queen sported heeled crimson wedges which had a corsage at the toe, and Hollywood-style shades.
