Jerome Dreyfuss, husband of French womenswear designer Isabel Marant, began his eponymous accessories line in 2002, after foraying in womenswear design — or what he called “couture a porter” — for several years. Dreyfuss’ debut bag collection, “Roots de Luxe,” set the tone for his trademark soft, leather bags. Each piece is designed in his Paris studio before undergoing a slow, environmentally friendly production process that supports artisanal methods of craftsmanship. Dreyfuss then aptly appropriates each of his creations a male name — such as Albert, Aldo, Bandit, Billy, Igor, Lucien or Momo — so women the world over can have fabulous humanized male shoulder companions. Celebrity devotees include Jessica Biel, Juliette Binoche, Jade Jagger, Diane Kruger and Audrey Tatou.
