Uniqlo Crew Neck Sweater I wore this once and then stored it in the closet. From the official website: Blended with high-quality 19.5-micron merino wool and soft-touch cotton. Machine washable. The silhouette has been updated to fit current trends, adding an overall relaxed feel. The hem ribbing is not too tight, providing a moderate fit, and is adjusted so it doesn't constrict the waistline when tucked in. The collar ribbing is slightly thicker to give it presence, so it won't interfere with inner layers like shirts. The cotton dyeing gives the color depth, resulting in a more beautiful knit. Length: 70cm Color: Blue系 (Blue-based) Neck: U-neck
