Inspiration comes from everywhere: books, art, people on the street. It is an interior process for me.

I had to work out that it was something that could move, without having everybody in spray painted leotards.

I'd seen the current stage production and the 1975 production of Chicago. I liked them both very much, but I didn't use them necessarily as inspiration.

Costumes are the first impression that you have of the character before they open their mouth-it really does establish who they are.

I always carry pictures of my children and grandchildren, which is what makes it all worthwhile. It's great fun that my grandkids get to see the costumes in Alice in Wonderland or a doll with grandma's dress.

In designing Supergirl, I wanted to embrace the past but more importantly, thrust her into the street-style action hero of today.
