This Alexander McQueen collection contained so many brushstrokes of nuance and reference that you were left itching to hear the design rationale behind them unstitched. Sarah Burton’s team is well-prepped, welcoming, and good eggs in general, yet seeing a collection as rich as this without that creator’s take seems like listening to a song with great lyrics played instrumentally. The sparse release notes asserted a “focus on silhouette,” and once you got beyond top notes including the sweetly naif early abstract-aping papercut prints and nicely spliced hybrid garments that also featured heavily in women’s pre-fall, it was these experiments in outline that lingered most in the memory.
