This is a long-sleeved top in a gray check pattern. I bought it several years ago and have worn it about 7-8 times. The elastic part of the back button is a little dirty, but otherwise, there are no noticeable stains. The sleeves can be made into three-quarter sleeves like in the third photo by fastening the inner buttons, so you can wear it even in the coming season. How about it for office casual wear?
