It was ugly. There was pushing, shoving, animal prints were flying. And then, after a ten minute display of quite how undignified human nature can be, it was over.

That's how the launch of H&M's Roberto Cavalli collection acted out last year, and this week the Swedish fast-fashion giant is continuing its mission of bringing high fashion to the hoi polloi with a collection from Rei Kawakubo's Comme des Garçons.

This tie-up may be less glamorous than the avant garde label's fancy store-in-store collaboration with Louis Vuitton in Tokyo, but at least there's some degree of symmetry with the Swedes: after washing, the seams are likely to be as deconstructed as the designs.
