All eyes have been on the Princess of Wales' style ever since she emerged in the royal spotlight as Prince William's love interest in the early 2000s.
Kate, who was once a twenty-something student rocking fun and flirty outfits, flitting between London nights out in glitzy mini dresses and sequin-adorned bodysuits, soon became royalty's best-dressed woman. Out with the old, clubbing outfits and flared jeans and in with the new era of Kate Middleton.
The royal, who tied the knot with the Prince of Wales in 2011, swapped out her ab-baring crop tops and low-slung skirts for smart tailored suits, glamorous pleated dresses and silhouette-skimming gowns that have now become synonymous with her unmistakable elegance.
Royal fashion throwback
In 2004, Prince William's wife-to-be had no official royal-style rules to abide by. As the summer sunshine brought clear skies to Oxfordshire, a cool and collected Kate embraced the temperatures in a tweed mini skirt elevated with a chunky woven belt.

Kate paired her mini skirt with a light and breezy pinstripe shirt, posing with a trench coat slung over her shoulder.

The royal-to-be finished off her look with a pair of tinted, rimless sunglasses and several boho bangles, letting her bouncy brunette locks fall to her shoulders in natural curls.

It's possible that the ring was a gift from William, who previously gave his wife a diamond eternity band, or a "promise ring" worth an estimated £1.5k from their early relationship.
Maxwell Stone from Steven Stone explained: "During their university days, William gave Kate a promise ring, and though it’s hard to be certain, recent footage of the royal couple suggests she may be wearing this sentimental piece again. The ring is set on a rose gold Victorian band, featuring two garnets - Kate’s birthstone - and pearls to represent William’s June birthstone."
