Kate Middleton is not a big fan of tiaras. In the years since she has been married to Prince William, she has only worn them a handful of times.
When it comes to tiaras, the royal family has a large and luxurious collection to choose from. Most of them are steeped in history and very significant.
Queen Elizabeth II would often loan some of her pieces to Kate Middleton and the other younger members of the family.
The rare times Kate Middleton wore a tiara
It made sense that she wore this royal piece for her wedding to Prince William, which also marked her official arrival into the royal family. For her "something borrowed" in 2011, the Queen lent the bride this Cartia Halo tiara for her wedding.
This jewel first belonged to the Queen Mother, Queen Elizabeth, who got it as a gift from her husband, King George VI. Queen Elizabeth II, upon turning 18, received this piece when her mom passed it down to her.
The Lotus Flower Tiara
It was not until two years later that the Duchess of Cambridge wore another Tiara. This time around, it was the Lotus Flower Tiara, which was on loan from The Queen as well.
Jewel expert Leslie Field told PEOPLE that the tiara was "a beautiful pearl and diamond piece" which once belonged to the Queen's late sister, Princess Margaret.
She would later wear the tiara again for a state banquet at Buckingham Palace.
Cambridge Lover's Knot Tiara
Kate Middleton has been spotted a couple of times wearing the Cambridge Lover's Knot Tiara, which once belonged to her later mother-in-law, Princess Diana.
She first wore it in 2015 for the Queen's annual winter banquet and we think she absolutely loved it.
In 2016, she donned the tiara again for the same Buckingham Palace event.
A year later, she wore the sparkly headpiece as she and the Duke of Cambridge arrived at the winter party.
Why doesn't she wear them more often?
No one can really say for sure why Kate Middleton does not wear tiaras as often as some of the other royals. But since there are no rules as to how frequently a royal is expected to wear them, it's safe to say it's just a matter of taste and preference. Perhaps, it's just not her style.
