This is a women's ensemble. There are no tags, so I'm not sure of the size, but I usually wear a size M, and this fits, so I think it's a size M. It looks like knitwear, but it feels nice against the skin. It's not itchy. I've worn it a few times, so there's some pilling, but it's still wearable. Measurements are approximate. The jacket is about 61 cm long, 39 cm wide at the shoulders, and 56 cm long in the sleeves. The inner garment is about 60 cm long, 39 cm wide at the shoulders, and 42 cm long in the sleeves. It's been stored at home, so it's used, but please understand that before purchasing.
