This is a UNIQLO Premium Lambswool V-neck sweater. The color is difficult to tell, but it's dark gray. I haven't worn it much, and it seems I won't be wearing it this year either, so I'm putting it up for sale. I've worn it about twice and haven't washed it once, so there's no shrinkage. Retail price: 3990 yen + tax I think it can be worn by both men and women if the size fits.
