Patrik Ervell’s show opened with a reinvention of the classic shearling-lined jean jacket in unwashed pale denim. The designer branched into ballistic nylon shoes (a Common Projects collaboration) and launched knitwear made from alpaca, deeming cashmere too common. He made a sensibly commercial showing of his bestsellers — hooded windbreakers and oversized blazers with slim pants — that fell a bit short on novelty. But under the economic circumstances, the conservative approach may be best.
