Discussing her multidimensional relationship including muse with St. Laurent she describes their trip to Moscow in the mid 1980's, when Gorbachev was still in office. there was a press conference at which Russian women asked him how to dress. Falaise, St. Laurent, et al thought they had come to advise Mrs. Gorbachev. Given their limited resources and clothes in Russia, women asked how they could dress. "My advise is this, when your husband buys a camel coat, you try it on too. Can you knit? Then knit a black turtleneck, knit yourself a skirt, and so on. You have wonderful traditional clothes. The Russian blouse is marvellous, so wear that. Take your belts and you can hammer nails in for decoration." Falaise thought St. Laurent's DIY ethic wonderfully original.

A photo from this same period in the film shows St. Laurent wearing a hand crocheted granny square vest with a geometric circle in the middle over a floral shirt. St. Laurent's advice is as pertinent now as it was then.
