Kirkland Signature brand navy blue long sleeve shirt. Lightweight, comfortable and flattering! I cut the tag out that has the material and care information because it was pokey, but it is most likely a cotton poly blend and I always machine washed in cold and dried on low. Please see photos for additional measurements and details. Please consider checking out my closet and boutique for many more items to complement this one! Make me an offer and bundle items to save on shipping! From a smoke-free, cat-and-dog friendly home. Measurements of garment laying flat on a surface: Armpit to armpit, about 23 inches Hips, about 26 inches Center back to hem, about 25 inches in front, about 27 inches in back Thanks for looking!
