This item is made from a disassembled women's kimono that has been washed with delicate detergent (listed as new and unused). The material is unknown, but it's a slightly thick fabric that resists wrinkles. A half-width obi (a type of sash) is used in the center, and the design of the collar utilizes its characteristics. A large pocket has been added. It seems like it would be useful for three seasons, layered with sweaters in the winter. Please purchase if you understand and appreciate kimono remakes. Flat measurements: Sleeve length (from center to sleeve end): approx. 58cm Width: approx. 64cm Length: approx. 114cm
