The woman was late because

M: Oh there you are, Vicki... At last... Where have you been? You’re late!
W: I’m sorry ... I’m sorry I’m late ... I went shopping ... and I forgot all about the programme.
M: Well, you’re here now - thank goodness!
W: Just in time!
M: What’s in your bags?
W: I’ve just been buying some new clothes - I’ve got a brand new outfit.
M: Wow! That’s fantastic ... Because first today, I want to talk about clothes and what we wear.
Why don’t you tell us about your shopping trip and your new outfit.
W: I love to try on new clothes.
M: Yes, I like seeing if clothes in shops fit me or not, too.
W: I’m doing some TV work later, and I have to dress up.
M: Yes, you better wear smart clothes if you’re going on TV.
W: So that’s why I bought this new outfit, Callum, I’m going to put on this brand new outfit.
M: Very nice. Well I’m not putting on smart clothes later—I’ve got to do some gardening so I need to wear my scruffy old clothes instead.
