Jane Birkin, the woman, not the coveted Hermès bag, spoke to WWD about her new album and her signature tomboy style.
WWD: A V-neck sweater and jeans is your signature look. Do you have a wardrobe of ballgowns at home that you secretly like to dress up in?
J.B.: Not at all. My thing is cashmere jerseys. I'm always peeking in [my daughters'] collars to see where they've bought their cashmere from. I just did a TV show a couple of days ago with [opera singer] Roberto Ayala where we sang "Je Suis Venu Te Dire Que Je M'en Vais." I had to make a tiny bit of effort. I'd bought a secondhand YSL suit for a cocktail in Buenos Aires and wore it with stockings and high heels and a camisole from Sabbia Rosa, where I used to buy my lingerie when I was younger. People were amazed; they're so used to seeing me in jeans. Then I threw it all off and got changed. I couldn't wait to get my shoes off, and the skirt was too tight. I'd rather be dressed as a man, and Lou [Doillon] had found these baggy men's pants [by John Varvatos] for me in New York. As soon as I'm in boys' things I feel like I'm 12 again. I'll go on tour in a white shirt and waistcoat. Lou is my costume designer; she has all the good ideas.
According to Wikipedia, this is how the Hermès bag came to be named after Birkin:
Hermès named and designed a handbag - the Birkin bag - for her in 1984 after the actress was seen in 1981 by the head of Hermès struggling with several bags while boarding an aeroplane. The Birkin bag has become one of Hermès' most popular and expensive handbags.
