The fabric is linen with nep and is slightly sheer. I am 158cm and 52kg and it fits me loosely. The size is marked as M, but it feels like M to L. Due to the nature of the fabric, there are wrinkles, but it's a blouse with a nice atmosphere that can be worn beautifully after washing. I bought it a few years ago and wore it with affection, but there are no stains.
