KOTN Cream Mockneck Lace

“The Lace Mockneck is made from a cotton and recycled polyester blend, featuring a refined herringbone lace pattern. Designed with a mock neckline, long sleeve and complemented by a unique open back detail with pearl button closures.” I love it but it fits small, no matter how hard i wish my shoulders to fit. XL on label but fits more like a M/L. Arms/shoulders are tight. I am usually an xl in most blouses. Missed the return window! Brand new!
