Gap White And Blue Stripes Button Down Shirt Size XXL

Gap white and blue striped button down shirt in size 2XL. The stripes are vertical and a couple shades of blue. There is some slight fading and very light yellowing on the back and collar. It’s faint so I’m not sure if it’s from wash and wear or staining. 100% cotton, machine wash. Pit to pit: 29 inches Length (measured down center of back from collar seam): 32 inches
