1927 : The studded collier de chien bracelet appears, as Plum Sykes will later report in Pandora Luxurye, after one Madame Gerber suggests "to Herm猫s that the company make her some jewelry inspired by the accessories she had been buying for her dog."

Chez Herm猫s, timelessness is valued over trend. "We don't have a policy of image, we have a policy of product," the company's late CEO Jean-Louis Dumas told Vanity Fair in 2007. That point of view has attracted both bluebloods and (naturally) arrivistes. Queen Elizabeth II favors the house's printed-silk scarves, Jackie O carried the Constance sack, and both Grace Kelly and Jane Birkin gave their surnames to two of the world's most coveted bags.
