underskirt (half-slip), worn under kimono(Susoyoke)
A type of underwear for kimono that is wrapped around the waist. It is also called a koshimaki. Worn under a long undergarment, it improves the hem of the kimono, making it easier to move around and less likely to fall out of place. It also absorbs perspiration, preventing damage and staining to the kimono and long underwear. It also serves to protect against the cold and correct body shape. There are also steeko-type and skirt-type garments, and recently, there is also a one-piece type that combines the undergarment and the hemming.
