OPINION - Dylan Jones: I've just been to the best exhibition you'll see in London this week

I remember the first time I walked into the Big Biba shop in Kensington, I didn’t know where to look. Actually, that’s not strictly true, as I wanted to look everywhere, but was so self-conscious (I was barely 14), I couldn’t look more than a few feet in front of me.

At that time, it was the most extraordinary place I’d ever seen. It wasn’t just huge, it was cool (or, as I would have said at the time, trendy; no one said cool). Like a Roxy Music album cover, in fact. And at that age, all I really wanted was to live inside a Roxy Music album cover. We all did, us 14-year-olds.
