Marie Gabrielle's 1900 wedding dress has no discernible seam or waist band and conspicuous darts running up her slender skirt. While Princess Royal Victoria's, Princes Alexandra's, Princess Beatrice's, and Princess Luise's wedding dresses are models of elegant frills and decoration, Duchess Marie Gabrielle's dress is a model of simplicity.
