Students may feel the criticism is harsh, but I think it's possible they haven't had criticism before. It's my job to point out when something is badly done, or when there's no point of view. To build a brand you have to have something about you. If not personality, then some thought process. I'm 40, and they're young, so they're meant to be informing me. They should be bringing me a book or something that I haven't seen, not like some obscure chant book by Dominican monks, but an image of the way they see the world.

It falls apart now. They used to be intrinsically linked. Now they've been driven so far apart that I don't think the one has anything to do with the other. Even more so: I think that there is almost a reaction against style, that brute ugliness somehow has been interpreted as being the way to go.

Of course, there's some you think, well I wouldn't let them in the door, but there's not many. It's very important to know that it's a mutual thing, that there is respect and a form of teamwork. With quite a few of them it can be traumatic, but there are moments in here when they do extraordinary things with their designs. There are things of beauty I get to see in this office.

When they first arrive, really, my eyes bleed! It's only when they're about to leave that they become people you might want to know.

Oh, they've been putting in the long hours ... But is that because they don't have the skills, and everything takes twice as long? Or do they put in these hours to avoid what they should be doing ... which is stopping and binning a lot of [their work]?

Don't crave fame, do what you do and just apply. I don't think many of them here today are that interested in fashion. Perhaps it's because there's not much going on. No punk, no reaction to something. I think we are in a waiting period.

I often ask students: 'Is this what you would show Tom Ford?' and they say: 'No, we'd have done more work' or 'We'd have dressed better.' So I say: 'Why don't you do that here?'
