This outer garment, part of a kasane set along with its counterpart labeled item 1708b, represents a tradition among wealthier Japanese families up until the early 20th century. It's crafted from a very fine creped silk, displaying a subdued black hue with a subtle bluish undertone. The flowers adorning this garment were meticulously crafted through embroidery, yuzen-painting, and brush painting techniques. It features five mon (family crests) and measures 49 inches (124 cm) from sleeve-end to sleeve-end, with a height of 61 inches (155 cm).
