This is loungewear that can be worn as a single layer, perfect for wearing around the house or when going to the convenience store. It's a gray sweatshirt material with a hoodie. There's no size tag, but it's about a size S. The waist and legs are loose, but the arms are a snug fit. The sleeves are 3/4 length, and the pants are short, reaching the thighs. It has two pockets. You can wear it over your underwear if you keep the zipper closed, or it's cute to open it up if you want to show off your innerwear. It's been used a few times, but it's in like-new condition.
