Lady Kitty Spencer wears Dolce & Gabbana's 'The Middleton' dress

Princess Diana's niece Lady Kitty Spencer found the perfect summer dressed inspired by her cousin-in-law the Duchess of Cambridge. The 26-year-old, who is the oldest daughter of the late Princess of Wales’ brother Charles Spencer, attended the Cartier Queen's Cup Polo final on Sunday (June 18) in Egham, England sporting the “Middleton Bow-embellished Cady Midi Dress” by Dolce & Gabbana.

The elegant frock was named after the Kate, who wore an altered, forest green version of the dress last September during her royal tour of Canada. The original design, which featured an embroidered Alice in Wonderland pocket watch motif, was a part of the Italian brand's fall 2016 collection, though Kate opted for a version without the gold embroidery.

The elegant frock was inspired by the Duchess of Cambridge.

“The Middleton” is currently available in both green and white on Net-A-Porter and retails for $2,675. The site describes the dress as "evocative of styles from the '40s" and suggests wearing the number to spring events with metallic heels. The white chiffon-trimmed piece features pearlescent buttons and a neat bow, in addition to puffed sleeves at the shoulders. Unlike Kate, who paired the dress wearing her glossy tresses down, Kitty swept her golden locks up into a ponytail for her day at the Guards Polo Club.
