This is a thin knit sweater from Uniqlo. I believe the material is the same as the Extra Fine Merino knit that they release every year. It's thin, so it won't be bulky under outerwear, making it easy to layer. The neckline has a boat neck design that makes your neck look beautiful. It's also cute worn off-the-shoulder. Recommended for the coming season. Material: Wool Color: Gray Sleeve Length: Long sleeve Length: Mid Pattern: Solid Neckline: Boat neck Season: Spring, Autumn, Winter Material: Wool
