This is a 100% cotton shirt with a striped pattern. I purchased it about 10 years ago at a select shop. It's a BLAIRE model from Ralph Lauren. It has a vintage feel and is cute. It's an item that will be useful in the spring. There is a stain on the right sleeve. Please refer to the fourth image. - Brand: The Kattail - Material: 100% Cotton - Model Name: BLAIRE - Design: Striped pattern The size is listed as L, but it feels a bit slim when worn.
