The color is a deep teal-like shade. It's labeled as a size M, but it fits quite snugly on a person who is 160cm tall and of average build, so it feels more like an XS-S size. It's see-through and cute! A five-sleeve shirt with a ribbon, made of polyester for a comfortable feel. - Brand: UNIQLO - Color: Dark Blue - Style: Ribbon shirt - Sleeve Length: Five-sleeve - Material: 100% Polyester Thank you for viewing.
