This is a long-sleeved off-white ribbed knit shirt made in Japan, purchased at Mitsukoshi Nihombashi about 12-3 years ago. It's made of 100% cotton and has a comfortable thickness, so it's not see-through. I loved it and bought several, wearing them often, but the neckline now feels a bit too revealing for me, so I'm selling it. Please understand that this item has been stored for a long time before purchasing. Length: 62cm Pit to pit: 44cm Sleeve length: 52cm (Measurements are approximate)
