The Met says: A rare example made from the heads and feathers of gulls, this accessory set represents the passion for using bird feathers and bird parts to decorate hats and other high-style fashion accessories in the 19th century. The practice ended in the early 20th century as birds were becoming extinct in order to supply the fashion industry. Even among examples from the period, this set stands out for its unusual design. The nestling of the two heads on the muff enhances the overall sense of warmth provided by the object, while the neckpiece draws attention to the wearer’s own swan-like neck. A set like this would have been been worn by an elite member of society who could afford to be somewhat unconventional in her taste.
