Just when you think Christopher Bailey has done everything that can possibly be done with a beanie, a trench-coat and a loosely fitted dress, he makes you fall in love with them all over again.

A couple of mitigating points. First, he tweaked his beloved style props slightly. The beanie is now a brimmed cloche, the shift dress is in gauzy, dip-dyed chiffon.

Secondly, he does what he does very well. When a model mooches wistfully down that catwalk in a sweetly subdued grey, gently flared coat, her sandy coloured chiffon dress fluttering slightly, her chunky wooden jewellery (this is a brand steadily evolving its accessories) nicely underplayed by her dun-coloured ankle socks, for a moment this almost looks like the fashion equivalent of cinéma vérité.

But the high-waisted tulip skirts and skinny long cardigans have been pre-crumpled, the muddy hems on those coats are an expensive trompe l’oeil, courtesy of state-of-the-art dyeing techniques.
