Brand: KBF Size: ONE Color: Blue Gray Material: 90% Cotton, 10% Linen Price reduced! 1649 yen → 799 yen The brand is probably KBF. (It might be KBF+...) I bought and used this several years ago. It's a used item with a worn feel! The size is indicated as size ONE, but it feels like a small M size. It's thin and easy to wear in the summer!!
