This item can be used all year round due to its thin material. It has a lining, so it is not see-through. I think it will be cold in the winter, so you can wear it with tights... Zipper on the left side. The pleated part is sewn on from the top. Length: 55 Waist: 36 (laid flat) The size notation is unclear, but the waist is 36 when laid flat. #Made in Japan #Tokyo Style Management number: 57
