Kate and Pippa Middleton's best twinning moments

The Duchess of Cambridge and Pippa Middleton are more than just sisters by blood - they're sartorial twins, too, given the wardrobe similarities they've donned throughout the years. <p>The duo are as close as ever and clearly taking style cues from each other. And with Pippa expecting her first child, she has a few years of maternity inspiration to look to in her sister, Kate. Though their years of borrowing from one another's closets have likely come to an end, it's still fun to see how they continue to influence each other. <p><strong>Click through to see all of Kate and Pippa's best twinning moments...</strong> <p>Photo: &copy; Getty Images

<h2>Hats off to the sisters!</h2> Was this a case of sisterly sharing? The furry brown topper Kate paired with a blue coat while on tour in Sweden and Norway in 2018 looks identical to one that her sister styled with yellow outerwear at the Cheltenham Festival in 2013. <p>Photos: &copy; Samir Hussein/WireImage and Indigo/Getty Images

<h2>A case of the blues</h2> For an awards ceremony at the Natural History Museum in 2014, the duchess donned a powder blue gown with a slit and a covered-up bodice. A year later at a fundraising gala, her sister Pippa slipped into a pleated Hugo Boss number in the same hue but with a plunging neckline. <p>Photos: &copy; Arthur Edwards - WPA Pool/Getty Images and Keith Hewitt/GC Images
<h2>Tartan toppers</h2> Kate kept the cool breezes at bay in Scotland in 2014 wearing a plaid jacket with black tights and boots.

<h2>Blushing beauties</h2> One thing the brunette beauties share in common is looking amazing in blush pink!

<h2>Shirt dressing in style</h2> The mother of three made a surprise appearance at a charity polo match in 2018 and, to the delight of thrifty fans, wore a pretty shirt dress form Zara.

<h2>Stripes and solids</h2> Fans delight in seeing the duchess dressed down, like the striped sweater with dark jeans that she sported at a 2017 reception for London Marathon runners from team Head's Together. Pippa wore a similar look while shopping in London in 2012, though she upped the chic factor with black slippers and dark sunnies. <p>Photos: &copy; Chris Jackson/AFP/Getty Images and TOE/Bauer-Griffin/GC Images
<h2>Cream coat dresses</h2> Like all of Kate's children's baptisms, Princess Charlotte's christening in 2015 called for a lovely cream Alexander McQueen ensemble - a coat dress with an a-line skirt and matching hat. Pippa was right behind her sister on Charlotte's big day in a similarly hued long-sleeved number and hat, though her shoes were nude rather than cream. <p>Photos: &copy; Chris Jackson/Getty Images and Max Mumby/Indigo/Getty Images
<h2>Soft waves and yellow lace</h2> Duchess Kate made a sunny appearance in Germany during her family's 2017 tour while Pippa traded her tennis whites for yellow lace at the US Open in 2012. <p>Photos: &copy; Samir Hussein/Wireimage and Uri Schanker/WireImage
