Barely worn once, maybe twice. Popular style, but not a great fit for me. The brand says it fits true to size, but it is loose in my opinion. I am usually a true medium. You can see the fit on the model pictures on this listing. Has never been around smoke or animals. FROM THE BRAND: Made of our everyday fabric, we love this knit for everyday wear at an everyday price. Easy, lightweight, and great for layering over dresses or button up shirts. 40% wool, 25% viscose, 25% polyamide, 10% cashmere. Made in China. Rolled edges at wrist and neck and a slightly longer back for an added detail.
