I had an argument with my students on why they want to present their work in an iBook, it's like your sister who has no design training, put on some outfits in the bedroom, took some pictures, sent them to Apple and after paying 40 quid, you have a portfolio! I can't believe it.

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.

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?'

It's a secret language, known to all different people, in different ways, that enables them to read a subliminal message without realising they're reading it. It affects people on many levels, and even people who think they're not into fashion, or reject fashion are then being informed just in the case of rejecting it. The fact that they had to react against it was a conscious decision.

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]?

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.
