Architecture is how the person places herself in the space. Fashion is about how you place the object on the person.
Of course there is a lot of fluidity now between art, architecture and fashion - a lot more cross-pollination in the disciplines, but this isn't about competition, it's about collaboration and what these practices and processes can contribute to one another.
People often ask me if I consider myself to be an architect, fashion designer, or artist. I'm an architect. The paintings I've done are very important to me, but they were part of a process of thinking and developing.
I have been interested in fashion since I was a kid. Then I lived in London, where it was more about costume and a personal statement of who you are than about fashion.
