I purchased this new from a MUJI store in February 2026 and home-cleaned it before wearing. I am selling it because the size didn't fit. It has only been tried on and is a new, unused item. It's a black and white striped shirt, size M. The back is lightly brushed for warmth and a soft feel. The cotton is organic cotton. Size: Length, Shoulder Width, Hem Width, Sleeve Length, Sleeve Length, Chest Width, Waist Width M: 63.0cm, 36.0cm, 43.0cm, 58.0cm, 76.0cm, 42.0cm, 40.0cm [Material] By lightly brushing the back of the fabric, we have created a clean surface that doesn't look like an undershirt, while also achieving warmth and a gentle feel. It has stretch for a comfortable fit. [Design] The slightly slim fit hugs the body, keeping you warm. The high neck that follows the neck provides protection from the cold and also adds an accent to layered necklines.
