Kate Middleton Glows in Festive Emerald Green Dress for NATO Reception at Buckingham Palace

The Duchess of Cambridge is clearly a big fan of Christmas as she's already sporting festive colors ahead of the holiday season. She wore a green dress, as always, with poise and charm.

Kate Middleton, 37, looked picture perfect for the holidays as she attended the NATO Summit on Tuesday. Despite wearing minimal jewelry, the duchess stood out in her ensemble.

The event included several world leaders, including the Queen, who hosted, as well as US President Donald Trump and his wife, Melania Trump. Photos are found below.

The Duchess of Cambridge stepped out for the affair reportedly wearing Emilia Wickstead's pleated midi-dress. The piece goes for $1,052 on Matchesfashion.com.

According to Cosmopolitan, the royal and the London-based designer have a longstanding relationship. Wickstead regularly customizes outfits just for Middleton.

This piece featured long sleeves with buttoned cuffs and a high neck. The duchess accessorized with a pair of diamond teardrop earrings borrowed from Queen Elizabeth II, reported the Daily Mail.

Some of who attended

Middleton's husband, Prince William, did not join her for the summit as he was off in Kuwait on royal duty. However, Prince Charles and Camilla did attend the event.

Also present were French President Emmanuel Macron, Canadian Prime Minister Justin Trudeau, UK Prime Minister Boris Johnson, and several other dignitaries.

A mini-date night

In mid-November, Prince William did accompany his wife as the two attended a Royal Variety Performance. The outing became somewhat of a date night for the pair.

Middleton again looked gorgeous in a black lace dress from Alexander McQueen. Prince William also wore black for the occasion, sporting a classic tuxedo and bowtie.

Middleton offset the all-black synchronization by wearing a pair of gold Erdem earrings and matching heels. She carried a black clutch bag with her.

Talking to the performers

The event, which took place at the Palladium Theatre, was held to assist the Royal Variety Charity. It consisted of some acrobatics. Two of the younger performers met William and Kate before getting onstage.

At another point, Kate revealed that her children wanted to join her and William, but she didn't allow them to because it was a school night. The three young royals have lots of fun events ahead, anyway.
