Because the fundamental human problem is that people are afraid of change.

I haven't yet made clothes that I have been totally satisfied with, and maybe I never will.

There's always a pattern in order to make a thing, but the starting point must be something I've never seen before. It's not two-dimensional, but it's like a sample. I work with patterns like a sculptor. I try to get [the team] not to work on a body, [but] to work on a free space, on a table. The work is basically on flat surfaces.

There are no limits - I endeavor to make clothes that didn't exist before.

If you have total freedom to design, you won't get anything interesting. So I give myself restraints in order to kind of push myself through, to create something new. It's the torture that I give myself, the pain and the struggle that I go through. So it's self-given, but that's the only way, I think, to make a strong, good new creation.

I started with wanting to think about witches, about strong women who have special powers - who are often misunderstood. Then I found some beautiful blue fabric, so I made Blue Witches. My creative process is always like that. Organic, text, theme, subtext, each day evolving and trying to make strong, beautiful clothes. It's that simple.

In the '70s, if anything, it was a more interesting time in fashion. It was a time when things were changing, especially in London.
