UNIQLO navy long-sleeved shirt dress, comfortable to wear with a cotton blend material. - Brand: UNIQLO - Size: L - Material: 70% cotton, 30% polyester - Color: Navy Thank you for viewing. This is a UNIQLO shirt dress I purchased a few years ago. It has buttons on the sleeves, allowing you to roll them up. It also comes with a waist ribbon (which I haven't used). I used it as a light jacket during the slightly colder seasons. I would wear it over short-sleeved or long-sleeved T-shirts. It's a long shirt, so it covers your hips nicely!
