Work in pairs. Practise the dialogue.
Hugo: Hi, Sammy.
Sammy: Oh, hi, Hugo.
Hugo: Those are cool trousers.
Sammy: Really? I think they're a bit baggy.
Hugo: They're supposed to be like that. I bought a pair like that a few weeks ago and they're so comfortable. They look really good.
Sammy: Maybe I'll buy them, then. That's an interesting shirt you're wearing.
Hugo: It's not really my style, but I'm going to a wedding next week and Mum wants me to wear something smart. What do you think of this one?
Sammy: That's better. It's expensive though.
Hugo: You're right, it is.
Sammy: But your mum does want you to look smart.
Hugo: Mmm, true. Why don't I try it on and then decide?
