It's a cotton knit. I think it's perfect for autumn. It has a slit in the back of the neck. The color in the third photo and onwards is closer to the actual item. There's a faint stain on the left sleeve if you look closely. Please understand that this is a used item and has been home-cleaned before purchasing. ● Size: FREE Shoulder width: 60 cm Body width: 59 cm Length: 62 cm Sleeve length: 42 cm Please note that there may be slight variations due to amateur measurements. ● Material: 100% cotton Greige turtleneck Washable, hand washable
