Used for parties and weddings. Velvet fabric. Because the fabric is velvet, it may look like there is dust, but there isn't. The sleeves are lace fabric, but there is an inner lining so you can't see through them. The color is ambiguous in the photos, but it is all black. Purchased at a dress specialty store for around 50,000 yen. It's knee-length on me, and I am 157cm tall.
