What does the man want to buy?

W: What can I do for you, sir?
M: I’m looking for a jacket for my son.
W: Come with me, please. Here are jackets for boys.
M: The black one is nice. How much is it?
W: Twenty five pounds.
M: Oh, I’m afraid it’s too expensive.
W: What about the blue one over there? It looks nice, too. And it’s cheaper.
M: But it’s a bit too small. Have you a bigger size?
W: Sorry, we haven’t. But we’ll get some soon. Will you come next week?
M: All right. I’ll come again.
