Thank you for viewing! This is a summer knit from BLANCE, a brand under the World group. It's thin and has a smooth feel, made of a material that's easy to wear even in the summer. Originally, it seems to have been water-resistant, but since it's old, it's probably best not to expect too much. It's see-through, so an inner layer is essential. I bought this used because I thought the pattern was interesting, but I couldn't pull it off, so I'm putting it up for sale. There's also a smell characteristic of used items, so please understand this before purchasing. Thank you.
