60 years to the April 1960 state visit that saw Queen Elizabeth welcome Charles de Gaulle in a most interesting hat. With a hybrid lampshade cloche shape, the hat’s flat crown curves in an angular hourglass curves to a short brim. Wide silk ribbon is used for a hatband and for the brim’s binding, which is unusually tied in a side bow. My thanks to reader Mary for suggesting this fascinating design!
