Women’s Medium Calvin Klein Butterfly-Sleeve Crewneck Sweater

I have a Calvin Klein crewneck sweater for sale. I bought this as a women’s size medium from the activewear section at Marshall’s and wore it maybe 2-3 times. It’s from their “Performance” collection. The sweater has a crewneck, butterfly sleeves, and says the word “Performance” across the back left shoulder. It’s very cozy - just doesn’t fit me right anymore. It’s been in a storage bin at my apartment (non-smoking but I have a dog).
