Which outfit are you most proud of?

[Buffy's] Halloween costume from season two episode six [Halloween]. That was my first season on Buffy, and they came to me and said that Buffy was going to be a Southern Belle.

I realised that we needed three or four of the same costume and that I had to build it, and I was terribly intimidated. That was the first time that I really had to build something huge like this, that was actually period.

I sat down and started sketching, and it was just there. Then, when I showed Sarah the sketch, she fell in love with the dress. Since then I've designed and sketched numerous costumes, but that one I'm the most proud of because that was my first and it turned out really well, And it was gorgeous and people still talk about it.

If you were given the chance to do a big BBC costume drama or a Merchant Ivory, would you really enjoy that?

If I was offered something like that I would do it in a second. I would absolutely love it. The times that I've been able to do period work, it's been so fulfilling to me.
