A Brit of Ghanian descent, designer Adrien Sauvage looked to both strands of his heritage for his debut show on the London’s men’s schedule. Lean suiting — Sauvage’s calling card since he launched his label in 2010 — was fashioned in fabrics that ran from jewel-toned velvets to silk cheetah prints in shades of gold and black and turquoise and black. But this season Sauvage also injected a younger, street-influenced feel with biker jackets in textured black or mustard leather, bomber jackets in color blocked fish skin and slim pants with zippers at the ankles, in muted purple tartan.
