As a young girl I was a real tomboy, only listening to myself. I carried on with this attitude even as a woman and when I first launched the Sonia Rykiel line, and said to women to remove their bras or when I designed sweaters with stitches inside out, everybody said to me that it was crazy and risky, but I ignored what they said and I did what I felt was right at the time.

The key to my collections is sensuality.
