This is a COS short-sleeved knit sweater from two years ago. It cost around 8,000 yen at the time. I've worn it about 5 times. There are some loose threads and stains here and there, so I'm selling it at a low price. (Please refrain from purchasing if you are concerned) The color is ivory, not pure white. It's a size S, but it has a slightly relaxed fit, so it can be worn without any problems even by someone who usually wears a size M.
