The size is listed as women's M, but I think it's about a Japanese size L. I noticed when taking the photos that there seems to be some color unevenness, like a stone wash. That also gives it a stylish look. The knit is sturdy and quite thick. Those who wear size M can wear it as an oversized fit. Please note that the color may differ slightly from the photos. It's bulky, so shipping costs will apply. Material...Cotton
