This is a black shirt from 10YC. I purchased it last November. As you can see in the image, the tips of the collar are slightly white. I washed it immediately after wearing it, so I don't think it's a stain. I have washed it before listing it, but it's a color that easily shows dust, so I recommend washing it again upon arrival before wearing it. No smoking, no pets. Instant purchase is welcome. Price negotiation is not possible (I will lower the price if it doesn't sell). Size ① Length ② Width ③ Shoulder Width ④ Sleeve Length ⑤ Collar Circumference 68.0 109.5 45.5 60.25 41.5 Easy care!

Pursuing comfort and texture. Polyester fabrics are highly functional, but sometimes they are difficult to wear or look cheap. 10YC pursued that. 10YC shirts dry quickly and are wrinkle-resistant. But they don't look cheap. The feel is not unpleasant, the comfort is good, and it feels like cotton.
