Lightweight jcrew crewneck. I cut the tag out because it was itchy but I’m almost positive it’s merino wool (but can’t guarantee!) Perfect for the office. Here’s the listing online which I believe is for this sweater: A classic pullover in our go-to merino wool—for lightweight... - warmth—finished with sporty rib trim along the neck, cuffs and hem. We like to think of this one as the slightly shrunken cousin of our beloved Tippi sweater, with a shorter (but not too short) waist that perfectly counters our favorite pair of high-rise jeans. Merino wool. Rib trim at neck, cuffs and hem. Dry clean. Import. Item B7786.
