GU Knit Shirt - Women's Size: S This is a see-through knit top, as shown in the photos. A black inner layer is recommended. It's perfect for this time of year when short sleeves are too cold, but one layer is just right. I've used it several times, but there are no noticeable stains. However, since it's been stored by a private individual and inspected visually, there may be oversights. We are looking forward to purchases from those who understand that this is a used item. #GU #Women's
