This inner garment, part of a kasane set with its counterpart labeled item 1708a, is a striking piece. It features a purple and mustard green geometric pattern across the silk upper body and sleeves, accompanied by a vibrant red silk lining covering a light cotton padding. The hem showcases a distinctive silhouette with a snowflake border against a black and beige background adorned with delicate flowers. The front displays nandine (Nanten) and pheasant's eye (Fukujuso) flowers, symbolizing turning hardship into luck according to an old Japanese saying. White plum blossoms bloom prominently on both the black exterior and interior. The bottom lining includes chrysanthemums and narcissuses, evoking the changing seasons from winter to spring alongside other flowers. Design techniques employed here include brush painting, yuzen-painting, and faux shibori dyeing. It measures 48.5 inches (123 cm) from sleeve-end to sleeve-end and stands at 60.5 inches (154 cm) in height, slightly smaller in both dimensions compared to the outer robe.
