This is a set of a kimono undergarment (size M) and tabi socks. I used it only once for a pre-wedding photoshoot in traditional Japanese attire. There are some wrinkles from washing, but they are on the inside and shouldn't affect wear. Tabi socks: Fukusuke, 4 clasps, flannel lining Kimono undergarment: Upper material: 100% cotton; Lower material: 100% polyester Care instructions: Machine washable Length: 120cm The following is quoted from Amazon: [Versatile] Can be used with all types of Japanese clothing, from everyday kimonos to yukata, furisode, and wedding attire. It's a simple, front-opening one-piece style with ties for easy wear. [Overwhelming Comfort] The upper body is made of cotton, which absorbs sweat and quickly wicks it away, providing excellent absorbency. [Reusable] It can be washed at home and is easy to care for. Recommended as an essential item for a beautiful kimono appearance.
