This is a GU ribbed turtleneck knit in white. The size is XL. It's thin and easy to wear, and the form-fitting shape is beautiful. It hasn't been worn much, so it's generally in good condition, but there's a faint stain on the chest (see image 4). It's not very noticeable, so I think it can still be worn. Basically, this assessment is based on a layman's eye, so please understand that and read my profile before making a purchase.
