WATCH: Kate Middleton Sings at Age 11 in a School Play

We all like to think of Princess Diana as the queen of fashion — and she was — but Kate Middleton is certainly this generation's style icon. Whether she's accompanying her husband at a royal engagement, walking the red carpet, or just running errands, Kate Middleton is sure to turn heads with her stylish ensembles.  

Her fashion choices inspire not only designers but also thousands of copycats (or copyKates, if you will). Who among us hasn't wanted to dress like the Duchess of Cambridge? The memorable sapphire blue Issa dress she wore to announce her engagement and her stunning Alexander McQueen lace wedding dress are just a few of our favorite looks. 

Even the fashion community, which is known to sharply criticize women for the way they dress has nothing but wonderful things to say about the duchess. "Kate is a beautiful woman inside and out, and a very powerful ambassador for British fashion," said Natasha Rufus Isaacs and Lavinia Brennan, the founders of the UK-based fashion brand Beulah London. "Kate Middleton is elegant, sensual, timeless," American designer Donna Karan added.

And though we might never have Kate's wardrobe, we can certainly use as inspiration not only for the way we want to dress, but for the person we want to be.

She carried a silk Prada clutch and on her feet were her trusty recycled nude LK Bennett heels. Her diamond chandelier earrings, which only upped the glam factor, were loaned to her by Queen Elizabeth back in October 2016 for a state dinner with the president of China and his wife. (We wouldn't give back those beautiful diamonds either!). 

At the event, Kate proved she wasn't just a pretty face when she cracked a joke about the cooking, which was catered by five world-renowned chefs. "William has to put up with my cooking most of the time," the duchess joked, so that night's meals were probably a treat for her husband.
