Special pieces. Derek Lam showed his Spring-Summer collection during New York Fashion Week. I like his signature 70s flair, white linen trenches with glossy black leather trim and elbow patches, future-vintage python pencil skirts brown leather blazers, colorful, chunky rib-knit sweaters, navy silk tapering trousers with deep white cuffs, tank dresses with holographic sequins. Lam delivers art-deco prints, modified jumpsuits, a-line skirts, snakeskin “Daytona” pumps, and bags. Overall, it’s sophisticated feminine collection.
