When you are having fun and creating something you love, it shows in the product. So when a woman is sifting through a rack of clothes, somehow that piece of clothing that you had so much fun designing speaks to her she responds to it and buys it. I believe you can actually transfer that energy to material things as you're creating them.
I take no notice of the trends. It has never concerned me at all. My job is to deal with what I want to deal with and reach an audience by doing so.
