Kate Middleton channeled a Princess Diana look from 1988 at this year's Royal Ascot

• Kate Middleton appeared to pay tribute to Princess Diana with a polka dot dress at Royal Ascot 2022.
• Diana wore a similar look in 1988 to Royal Ascot, which is known for its extravagant fashion.

Kate Middleton took a style cue from Princess Diana with a polka-dot dress at this year's Royal Ascot.

According to Vogue, The Duchess of Cambridge wore an Alessandra Rich dress and a Sally-Ann Provan hat to the traditional carriage procession at Ascot Racecourse on Friday. Diana wore a very similar look to the same event in 1988, donning a dress by Victor Edelstein and a hat by Philip Somerville, according to Getty Images.

People reports that Kate accessorized the look with a pair of South-Sea pearl earrings that once belonged to Diana.

Both Diana and Kate's dresses feature long sleeves, shoulder details, and a cinched waist. While Diana's hat matched the pattern on her dress, Kate contrasted her ensemble with a dark hat topped with floral embellishment. She finished the look with a pair of brown heels and a brown clutch bag.

Kate's look also drew comparisons to Julia Roberts' brown polka-dot frock from the classic 1990 film "Pretty Woman."

Royal Ascot, a five-day annual horse racing event attended by the royal family, is known for its over-the-top fashion. Kate's mother Carole Middleton also made headlines on the first day of the races Tuesday when she appeared to borrow a fuchsia dress her daughter originally wore in 2021.

The British royal family members are known to take styling tips from one another. Both Kate and Meghan Markle have paid tribute to Diana with fashion through the years, including the military-style coat Kate wore on Remembrance Sunday in 2021.

At this year's Invictus Games, The Daily Mail reported that Meghan wore a Cartier Tank watch that previously belonged to Diana.
