on Friday, February 5, 1954, the Queen and Duke of Edinburgh continued their visit to Sydney with stops at Hyde Park, Sandringham Gardens, Macquerie Place (where they planted two trees and opened the Australian Memorial Driveway), Concord Repatriation Hospital and a children’s rally in Concord Park. The Queen topped a silver lace dress with a white triple layered calot hat. The hat raised around the front in a near bonnet shape and was trimmed with a bow on one side and a covered button on the other.
On Sunday, February 7, 1954, the couple attended Sunday service at St. Andrew’s Cathedral led by Archbishop of Sydney Howard Mowll. Her hat appears to be a ruffled (or floral?) calot worn high on the head to frame her face.

The calot hats are very sweet. Just like now if the Queen finds a style that looks good on her she sticks with it!
Loving this series. Great reminder how young and fashionable the Queen was!
So far this is the 1954 Calot Tour. Obviously trendy at the time but I’m not loving them. What I am loving is that lace dress. Gorgeous!
