Uniqlo's Washable Mid Gauge Crew Neck Sweater, size M. It can be worn without bunching up even when layering, allowing for a neat and tidy look. The color is blue, but it's a calm shade, so I think it's easy to match with other items. Worn a few times, and I think it's in relatively good condition. Please refrain from purchasing if you are sensitive to used items. - Color: 67BLUE - Material: 95% Acrylic, 5% Wool - Size: M
