This is a short-sleeved knit from COS from two years ago. It was around 8,000 yen at the time. I've worn it about 5 times. There are some loose threads and stains in places, 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 that I, who usually wears a size M, can wear without any discomfort.
