The Duchess, who was dressed characteristically stylish in a green Smythe blazer, white top, and wide-leg pants, shared a sweet moment with a young royal fan while meeting members of the local community. The bold look was a departure from Kate's usual style, drawing comparisons to her sister-in-law who is often seen in wide leg pants.
Kate usually opts for dresses or skinny pants when attending royal engagements.
On Tuesday, the Duke and Duchess of Cambridge joined Her Majesty at the Diplomatic Reception held at Buckingham Palace.
It comes after the Duchess of Sussex started the trend by wearing wide leg pants for a number of royal engagements.
The Prince, who was a helicopter pilot for the East Anglian Air Ambulance, and also served with the Royal Air Force, was even reunited with some of his former colleagues in Cyprus.
William and Kate could not help themselves and indulged in a little festive fun after staging a Santa's grotto in the grounds of their Kensington Palace home for more than 200 wives, girlfriends, parents and grandparents holding the fort at home.
The duchess greets children in Cyprus
William and Kate were delivering cards and gifts from back home after they hosted a party at Kensington Palace yesterday for children and partners of some of those based in Cyprus.
Kate looked very festive for the occasion in a stunning red checked skirt.
The Duchess told the military families at the children's party that, as the wife of "someone whose husband has served", she understood "how it feels when a loved one leaves home to do the job they're trained for".
They seemed to love it and looked so shocked! "George said to me this morning, "Where are you going daddy?' and I said, "I'm going to see some pilots who fly fast jets", William said".
She accessorised with pearl earrings and the Cambridge Lover's Knot tiara, which previously belonged to her late mother-in-law Princess Diana, and proudly wore the yellow ribbon of the Queen's Order pinned to her chest.
