Oversize cotton sweatshirt. It's faded from wear, but still has plenty of life left! The size is 'one size (OS)' but it’s like a large or extra large. I’m usually a small in sweatshirts and it fits oversized and cozy. NOTE: The red color looks like a warm red in the images, but it's actually a cooler red. Please check the last image to see what it looks like in person. Measurements (front side): Length: 26.5 inches Chest: 23.75 inches Waist: 24.5 inches Sleeve length: 20.5 inches Bottom opening 21.5 inches
