Wilhelmina is wearing a satin and ostrich feather toque, called Louis Le Grand. The photograph was one of four promotional prints for Mr John’s Dashing Degas collection for autumn and winter, 1965. The name of this hat could be a reference to Louis Legrand, an artist and contemporary of Degas, also known for his paintings of ballet dancers.
