This is a plant-dyed T-shirt dyed with mugwort leaves and iron mordant. The iron mordant deepens the color, resulting in a deep, grayish-black finish. While the color is surprisingly strong for a natural dye, it also has the soft texture unique to plant dyeing. With a chic and calm atmosphere, this color is easy to match with adult casual styles. Each item is dyed by hand, so no two are exactly alike. Please enjoy the uneven dyeing and color variations as unique characteristics of plant dyeing.
