Thank you for your interest. This is a UNIQLO men's soft touch turtleneck T-shirt. It has a simple design and long sleeves. It's a turtleneck (high neck) and I think it can be worn under a suit, sweater, or outerwear at this time of year. It's a simple black color that can be worn casually or in the office, and it's 100% cotton, so I think it's comfortable to wear. It's a men's (for men) M size. It's a shirt with a soft, 100% cotton feel. Thank you.
