But the red dress wasn’t Kate’s only homage to the royal family that day. The royal mom of three chose to wear Queen Elizabeth’s stunning diamond and pearl drop earrings as she stepped out for the royal baby’s public debut.
On loan from the Queen, the earrings are one of Kate’s favorites. She has worn them on several occasions, including during a 2016 visit to the Mauritshuis gallery in Holland, where she viewed the iconic painting, “Girl with a Pearl Earring.”
The Queen last wore them herself during her Diamond Jubilee celebrations in 2012.
One of the best perks about having the Queen as your grandmother-in-law is the access to her royal jewelry box! From the Queen’s own wedding bracelet, the Lotus Flower tiara and her diamond-encrusted maple leaf brooch, Kate has borrowed several amazing pieces from Queen Elizabeth over the years.
Perhaps the most famous piece of royal jewelry Kate borrowed is also her first: the delicate Cartier “Halo” tiara she wore on her wedding day in 2011.
“It completes them,” royal biographer Ingrid Seward tells PEOPLE in this week’s cover story. A friend of the couple notes that Kate, 36, “is one of three siblings, and it’s a good family size. Boy-girl-boy is pretty cool as well.”
Parenthood, the friend adds, “suits them really well. They are enjoying it and are very happy.”
