It's undeniable that tie dye is back, and not just in the look I'm at Coachella! way or the traditional Japanese indigo way—lately I've been seeing the classic spiral tie-dye shirts that we all remember from summer camp, especially in monotones. And why not? Tie dye is still totally fun. I love these ultra soft unisex Jungmaven shirts ($67) made from a blend of hemp and cotton, they're American-made and manufactured sustainably.
