If Thailand’s northern region could be said to have an iconic item of clothing, this would be it. Known as suea maw hawm, these cotton shirts are worn by everyone from schoolkids to chefs, and it’s easy to see why: they’re tough, light, loaded with handy pockets and, because they’re dyed with real indigo, stains barely show, and they fade over time, just like a trusted pair of blue jeans. We’re offering shirts made by Mohom Ban PaLuang, a second-generation indigo dyer in the village of Ban Thung Hong, in Phrae Province, northern Thailand, and one of the only remaining producers who still dye with natural indigo.
