This is a Uniqlo "Kiwami Warm" Heattech Cashmere Blend Crew Neck T-shirt. The color is natural, and the size is S. I purchased it in December and wore it once, but the neckline felt too tight for me, so I'm selling it. It has been home-laundered. Since it was only worn once, I believe the condition is good, but it is a used item, so please consider purchasing it if you understand this.
