Iromuji (色無地) (lit. "solid colour") are monochromatic, undecorated kimono mainly worn to tea ceremonies. The dyed silk may have a flat woven pattern - iromuji suitable for autumn are often made of rinzu silk. Some edo komon with incredibly fine patterns may be suitable for tea ceremony, as from a distance they are visually similar to iromuji. Iromuji may occasionally have one kamon, though likely no more than this, and are always made of silk. Shibori accessories such as obiage are never worn with iromuji if the purpose of wear is a tea ceremony; instead, flat and untextured silks are chosen for accessories. - Wikipedia, 13/5/2020
