Until recently, I always used to feel a bit weird and eccentric when I wore a hat. "That's the thing," says milliner extraordinaire Philip Treacy in a reprimanding tone, "People have been encouraged to think that hat wearing is for eccentrics; you know, the kind of women that like to wear hamburgers on their head at Ascot, or the older generation, but that has never been true. It's only now, thanks to MTV, that the young generation are wearing them, and realising how good they look."
