Nightwear, pajamas, loungewear... This is a top and bottom set. I think you can wear it casually. I think it's for men. Brand new, unused. Photos 8 and 9 are of a different item that was taken for photography purposes. I think the design is different. The sleeve length and the length of the pants may be different. Since it is unopened, I cannot confirm, so please refrain from purchasing if you are concerned. In my opinion... the sewing seems to be a bit loose. I may change the shipping method from Rakuraku Mercari Bin to Yu-Yu Mercari Bin. I will fold it for shipping. Although it is new and unopened, it has been in someone's possession, so I would appreciate it if you could understand.
