I bought this about 3 years ago and wore it about 5 or 6 times. There are no particular stains or anything. Below is the product description from the website: [Design] A ribbed knit sweater with a beautiful silhouette, featuring a boat neck and sleeves. The waist has a three-dimensional accent with tucks, making even simple outfits look subtly elegant. The length is just right, falling to the waist, and it pairs well with a wide range of bottoms. [Fabric] A ribbed knit with a moderate surface texture and a narrow pitch. The moderate crispness of the rayon and nylon blend is perfect for spring. This product is mainly for spring wear.
