File these under: collectibles. London’s Man show sent out memorable pieces from three Brit designers: Nicomede Talavera, who grunged up gingham; Liam Hodges, who screen-printed boy scout’s badges onto khakis; and Bobby Abley, who reimagined “Little Mermaid” for the skater set, splashing Ursula and her ilk on neoprene and throwing in some tinsel mohair into the mix. Gender- and genre-bending in equal stead.
