It takes one butterfly to produce the 300 eggs needed to make one silk carré. I’m not sure how many butterflies are hard at work on Hermes’ Maxi Twilly –– a great big swath of heavy twill jacquard silk worn on the chicest necks of the Cote d’Azur. I’d wear mine, as a cumberband around my waist. Unless, I am invited for a spin in someone’s MGM roadster, in which case that scarf will be on my neck, à la Ms Kelly.
