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 moderate thickness, so it's not see-through. I loved it and bought several, wearing them often, but the neckline is no longer suitable for my age, 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)
