Uniqlo Mock Neck Long Sleeve T-shirt, Set of 2! 100% Cotton Rib: 70% Cotton, 30% Polyester I purchased these here, but I'm selling them because they don't fit me anymore since I've gained weight. I only tried them on, but there is one yellowed stain on the lower left side of the white one. The fabric is sturdy, so I think they can still be worn for a long time. The fabric is thick and not see-through. They have a relaxed width and a neat length, making them easy to pair with pants or skirts. Measurements: Width approx. 55cm, Sleeve length approx. 48cm, Sleeve opening approx. 25cm, Length approx. 55cm. These measurements are approximate. They will be compressed and shipped in a bag, so there may be creases. Please refrain from purchasing if you are sensitive to this. Season: Autumn
