Menswear's blue period is officially here. Not just for jeans anymore, indigo dyes have been utilized for T-shirts, chinos, outerwear, and button downs. West coast shop Unionmade has done several iterations of their indigo collection, and J. Crew has dipped several items in the dye too. Even younger, independent labels like The Windmill Club have given their slim-fitting oxfords the indigo treatment. Japanese brands like Kapital and Blue Blue Japan are leading the charge with next level indigo duds like v-neck pocket tees with old eastern influences and chore jackets made of textured sashiko fabric, used for things like judo uniforms.
