Princess Kate is having a retro moment!

Last week, the royal sported a ’60s-inspired pill box hat that perfectly channeled Jackie O., and on Friday, she took us back to the ’80s with a headband!

And not just any headband – the royal opted for a plastic, tortoise-shell band to hold back her long brunette locks during an air show in Gloucestershire with Prince William and Prince George.

Known in the U.K. as the “Alice band” – named after Lewis Caroll’s Alice, who wore a ribbon around her head in the original illustrations – the hair accessory has a following among royals (even if it is largely considered anti-fashion!).

Princess Diana was a frequent wearer of the Alice band in the ’80s. And Sarah Ferguson has been spotted wearing the hair trend on several occasions. Ferguson even had her daughters, Princess Eugenie and Princess Beatrice, sporting the accessory as kids!

Kate, who also wore the same printed band during a recent family picnic, may have adopted the hair trend to keep her locks from falling in her face as she tends to Prince George and Princess Charlotte.

Or maybe it’s just a great way to protect her elegant blowout from the unpredictable, windy British weather!

Even though Kate’s latest hair accessory may come as a surprise, there’s no denying she makes it look effortlessly (and royally!) good.
