Queen of Royal Rewears! See All of Kate Middleton's Best Recycled Outfits

Guests at the inaugural Earthshot Prize awards in October 2021 were asked not to purchase new frocks or suits for the evening. Kate Middleton recycled a lilac gown by Alexander McQueen that she previously wore a full decade earlier in Los Angeles.

Kate's long-sleeved houndstooth dress with a bow neck by Zara made a reappearance in October 2021, nearly two years after she wore the same piece during an away day in Bradford in January 2020.

Third time...still a charm! Kate's love for the Duchess Wool Blazer by Smythe has persisted through the years, from her 2011 trip to Canada (where she wore a navy jacket) to her 2016 return to the Great White North (where she debuted an olive green version). She pulled out the olive blazer again to spread Christmas cheer to military families in Cyprus in December 2018.

Kate pulled out her teal Emilia Wickstead dress, featuring a pleated skirt and long sleeves, for her November 2018 outing with Prince William. She previously wore the dress during their 2014 trip to New Zealand (paired with a fascinator!) and a 2015 visit to the Centre for Addiction Treatment Studies.

This cranberry Paule Ka suit made its debut in 2012, at an appearance at Middle Temple. In 2017, when she brought it back out, she added a turtleneck and her trusty Stuart Weitzman boots. Then for a November 2018 outing, she swapped in velvet pumps and a matching hair bow.

If you thought Kate's blue dress by Eponine London during her charity outing with Prince William on November 2018 (right) looked familiar, you may have recognized it from when she previously wore it in January 2017.

Kate sported an emerald green coat with velvet details by one of her favorite brands, Catherine Walker, for the Centenary of the Armistice at Westminster Abbey in November (right). She previously chose the piece for when she and Prince William met with soldiers of the 1st Battalion Irish Guards (and took a sip of Guinness!) following the 2017 St. Patrick's Day parade in London.

So what if a dress sits in your closet for six years?

The mother of three joined Prince William at the 2018 Tusk Conservation Awards in November in a teal floor-length gown with lace cap sleeves and a belted waist by Jenny Packam that made its debut on Kate back in 2012! However, she opted to let her hair down in loose waves for the second time around.

Kate recycled a blue Jenny Packam for an October 2018 visit to the Imperial War Museum London, where she viewed letters relating to the three brothers of her great-grandmother, all of whom fought and died in World War I. With her hair down and covering the outfit's structured collar, it was hard to spot that it was a rewear from September 2016.

The mother of three stuck to her tradition of rewearing outfits when attending weddings at Princess Eugenie and Jack Brooksbanks' big day in October 2018. Kate wore a burgundy ensemble by her own wedding dress designer, Alexander McQueen, and a matching velvet beret by go-to milliner Philip Treacy. It was a twist on the pink light version of the dress she wore for the 2017 Trooping the Colour.

Fans experienced some style déjà vu when Kate stepped out in October sporting a light purple Emilia Wickstead dress featuring long sleeves, a piece she previously sported during her family's visit to Germany in July 2017.

No piece from Kate's wardrobe has seen as much rotation as her favorite go-to boots, her trusty Penelope Chilvers long tassel boots. They made their latest appearance when the royal returned to public duty from her maternity leave in October, but the shoes have been in Kate's closet since 2004!

Another wedding rewear! Kate added a floral headpiece to her cornflower blue coatdress by Catherine Walker & Co (which she previously wore when the family arrived in Berlin during their July 2017 tour) for her pal Sophie Carter's September wedding.

At the May wedding of Prince Harry and Meghan Markle, Kate appeared to pull an epic royal rewear with an off-white structured-collared coat dress.

In July 2015, Kate wore a very similar piece to Princess Charlotte's christening. She pulled out the ensemble again at the Queen's official birthday celebrations, Trooping the Colour, in 2016.

Kate pulled one of her favorite maternity dresses out of the closet for an outing in London in January 2018. The $85 blue and green floral print dress by maternity brand Seraphine was also worn a couple times while pregnant with Charlotte.

Kate first wore her yellow Roksanda Ilincic dress for a trip to Australia on April 16, 2014, then decided it was the perfect piece to wear to Wimbledon in 2016.

Seeing triple! Kate wowed in red with a Luisa Spagnoli skirt suit on various occasions, ranging from 2011 to 2017.

Kate wore a purple coat featuring black velvet trim by Séraphine during a trip to New York City in 2014, then pulled it out again for a visit to the Rugby Portobello Trust in 2017.

Kate was seeing spots twice — first with a fascinator during the Princess Cruises ship naming ceremony in June 2013, and revived the outfit for a visit to the Turner Contemporary Art Gallery on March 11, 2015.

Another Hobbs dress got the double dipping treatment. Kate wore this grey patterned dress in 2012 and again two years later for a trip to New Zealand.
