LONDON • It was Sunday morning, the fourth day of London Fashion Week, and as sunlight streamed through the vaulted skylights of the Victoria Miro art gallery in East London, Victoria Beckham was preparing to unveil her latest collection.

There was no runway, however, or front row or backstage scrum. Like all but two of the designers showing as part of a pared-back schedule here, Beckham had dispensed with a fashion show.
