Nice cotton and sewing. Has knee-length lining so you have nothing to worry about. I normally wear M but choose L to get the oversized look and it’s exactly what I want. The hem reaches my ankles perfectly. I think the length of the bust area seems a little shorter than the photo? But I find no apparent issues in that. My only complaint is that you have to put it over your head to put it on, so it’s a little confusing since it’s very long 😂 I guess I’ll have to remember that the label inside the lining needs to be on the left side!
