Dressing in all-indigo was definitely an export of Japan, but was readily embraced by guys stateside and worldwide. Visvim and Blue Blue Japan led the charge in creating grail indigo items, but brands like Unionmade and J.Crew were also on board when it came to feeling blue. All-black everything has always been around, but the dye du jour this year had guys, ahem, dipped in indigo. Chinos, button-downs, T-shirts, and all sorts of workwear got the blues treatment, and at times it seemed like the most stylish guys could be spotted by their blue-hued fingertips.
