Purchased from Uniqlo. The white sweater still has the tag, and the two striped sweaters are unworn, although the tags have been removed! I usually wear a size M at Uniqlo, but these sweaters fit snugly, so even if you usually wear a size M, you might be able to wear an XL. Also, a key point is that you won't look bulky even if you wear Heattech or other thermal underwear underneath. This is a set of three. *Due to bulkiness and shipping costs, I'm asking for this price!*
