There was no sacrificing style when Kate Middleton stepped out in West London wearing a tartan cape and olive-green scarf recently.

Just beginning to show, the Duchess was shopping for jeggings at The Gap - a nod to her pragmatic, low-street tendencies. She complemented the breezy look with an easy, loose ponytail.

As a public figure, Kate Middleton has been lauded for her eclectic taste in fashion. The fashion-forward royal attended Queen Elizabeth II's Diamond Jubilee Pageant in Alexander McQueen, but kept things sensible with an Orla Kiely ensemble to visit Prince Charles' Foundation for Children and the Arts. Duchess Kate is also a fan of re-wearing outfits - virtually unheard of in the A-list world - including an Emilia Wickstead dress she has donned on more than one occasion.

The Duchess is reminiscent of another beloved royal fashion icon - Diana, Princess of Wales. As well-known for her international charity work as she is for her stellar style, Kate's commitment to goodwill and sartorial savvy closely parallels the late Princess' dedication to both charity work and the progression of fashion.

Diana was largely involved with homeless charity Centrepoint and the National AIDS Trust, but also was a champion for the fashion industry. She even led the two worlds to collide in 1997, when she auctioned off 79 of her favorite gowns at a Christie's auction and raised $6 million for AIDS and breast-cancer charities.

Kate Middleton's high/low sartorial choices are truly fit for a People's Princess: a member of the monarchy who can relate to the public by wearing garments at a lower price point. The fact that she has favorites that she prefers to re-wear makes her fashion status attainable. She is so influential in fact that the blue Issa London dress she wore to announce her engagement to Prince William is now available in maternity form.

Duchess Kate certainly lives up to her lineage as a 21st-century icon that blurs the lines between pop culture and Princess. Let's be honest, working toward the greater good is even better when you look super-stylish.
