Authentic Calvin Klein. Subtle style, brand name on the chest... you can enjoy the attention. This is a Japanese M size. I wear an L size, but someone who wears an L size can also wear this. It's a T-shirt you can wear casually. The gray ringer neck and sleeves are stylish. It feels good even at this price. I've deliberately listed it as having scratches and dirt. Please refrain from purchasing if you are sensitive or expect perfection from used items.
