Kate Middleton's best evening dresses

We take a look at the best evening gowns worn by the Duchess of Cambridge, née Kate Middleton.

Kate may have been expecting her second child, but she revisited a pre-pregnancy favourite during her official tour of New York with Prince William in December 2014. Kate wore this stunning dark blue Jenny Packham gown for the St Andrews 600th Anniversary Ball.

The Duchess had previously donned the same Jenny Packham design for an Action on Addiction Gala dinner in October 2013, but chose to wear her long hair down in loose waves instead of a chignon.

Kate was glowing in this black lace Diane Von Furstenberg gown at the Royal Variety Performance in November, just two months after announcing her second pregnancy. Accessorised with a sparkly black clutch and Lola blue topaz hoop earrings by Kiki McDonough, she looked suitably glamorous for the occasion.

All eyes were on Kate when she attended the Wildlife Photographer of the Year Awards in this striking pale jade coloured Jenny Packham gown in October 2014.

Kate loves this Alice Temperley dress so much she wore it not just once but three times, most recently at a screening hosted at the National History Museum in December 2013.

Duchess Kate made her first red carpet appearance following the birth of Prince George in style with this striking silver sequin dress from one of her go-to designers, Jenny Packham.

Kate wore an eye-catching white and gold gown from one of her other favourite designers, Alexander McQueen, for an official dinner hosted by the King and Queen of Malaysia in September 2012.

A daring move away from the norm, Kate's teal Jenny Packham gown with embellished waistband was a bold and beautiful choice for the Olympic concert in May 2012.

Kate opted for a pretty pastel Alexander McQueen dress for the BAFTA Brits to Watch event in Los Angeles. With a cinched waistband, soft pleats and complementing silver clutch, it was the epitome of Hollywood glamour.

The Duchess was pretty in pink in this sequin embellished Jenny Packham number for the ARK 10th Anniversary Gala Dinner in June 2011, just months after she tied the knot.

For the hotly anticipated Spectre premiere in October, the Duchess turned heads in a stunning pale blue Jenny Packham gown as she stepped onto the red carpet at the Royal Albert Hall in London.

The beautiful brunette put her slim physique on display in the dress, which featured crossover details that showed off a hint of Kate's lower back.

The stylish 33-year-old paired the showstopping gown with a silver box clutch and her favourite Jimmy Choo sandals.

For her first state banquet, Kate chose to wear a red Jenny Packham gown which featured cap sleeves, a sweeping train and sparkling embellishment details.

The 33-year-old completed the look with the Lotus Flower tiara.
