Polyester This is a washable han-eri (collar) embroidered with a maple leaf and Togetsukyo Bridge in a pale vermilion gradation on soft white silk-like chirimen (crepe) fabric. The moon reflected on the water surface under the bridge is also embroidered, creating a wonderful design. How about wearing it with紬 (tsumugi) or komon (small patterned) kimono for an autumn outing? There are streak-like stains on the part that touched the skin when worn. The part that is visible when worn is clean, but this is a used item, so please understand this before purchasing.
