This is a high-neck innerwear from the workwear brand EVEVRIVER. Size L. I bought it in the winter of 2023-24, but the high neck felt a bit tight, so I hardly wore it. I kept it thinking I might wear it this winter, but I haven't worn it at all. The condition is good, and it seems a waste to throw it away, so I hope it can be passed on to someone who will use it.
