Princess Charlotte has a long history of twinning with her great-grandmother, Queen Elizabeth, and Monday was no exception.

One day after the 3-year-old joined her brother Prince George and her parents Kate Middleton and Prince William at Trooping the Colour, the young royal was seen enjoying a day in the sun at the Maserati Royal Charity Polo Trophy at Beaufort Park — where William was playing in a charity game.

Rocking little pink sunglasses that perfectly matched her sundress, Charlotte looked happy as can be.

But royal watches noticed something else: just how similar she looked to the Queen.

Queen Elizabeth has been spotted wearing dark sunglasses during recent events, including two garden parties at Buckingham Palace last month.

On Friday, a palace spokesperson told PEOPLE the Queen, “underwent a short, planned procedure to treat a cataract last month.”

Cataract surgery is performed to treat cataracts, which can cause blurry vision and increase the glare from lights. The procedure, which is common and generally safe, is typically performed by an ophthalmologist on an outpatient basis.

Colors may seem brighter after surgery because the patient is looking through a new, clear lens, which is likely why the Queen has been sporting a rare pair of shades.

Though Charlotte’s shades are simply a fun fashion choice, they do make her look even more like her great-grandmother.

Previously, the littlest royal looked just like the monarch in school photos released back in January.

From their captivating gazes to their matching royal hair part, Charlotte has inherited the very best of the 92-year-old monarch.

The royal relatives also both share a love of pink. Kate recently revealed that it’s her daughter’s favorite color, which explains why Charlotte he has worn lots of pink dresses during royal outings. The Queen is also often spotted wearing bright pink ensembles while performing her many public duties.
