This regal beauty was the coronation gown of Queen Marie of Roumania, a granddaughter of Queen Victoria. It is part of the permanent Queen Marie collection at the Maryhill Museum in Washington state.
Another collection of interest to the fashion enthusiast is the Theatre de la Mode French fashion mannequins and design sets on temporary loan to the museum. More information is available on the Maryhill museum website. I snapped a few pictures during my visit in May, but they only hint at the marvelous couture detail of these miniature ensembles; my photography does not do them justice!
