I've done a few costume dramas, and people say, 'What was it like wearing the costumes? Did they really help you with your character?,' and most of the time it doesn't make any difference. You're wearing something a bit weird, and it's sort of uncomfortable, but it doesn't really have a huge impact on the part that you're playing.
When you talk to women who were working as print journalists or in broadcasting in the '50s, and then you talk to women who were working in the late '60s, there's an enormous difference. There had already been a huge transition. Then, of course, you get well into the '70s and there were women with children working.
