Joseph Abboud Men's Button Down Shirt, Blue with Stripes, Size 15 1/2 32/33

Joseph Abboud men's button-down shirt. Blue with purple stripes. Size 15 1/2 32/33, Regular Fit. Worn only a handful of times by my hubby, been hanging in a closet otherwise. Slight stain on the inside of the back collar just above brand tag (visible in close-up picture). Not at all noticeable while wearing. Pet-friendly, smoke-free home. Thanks for looking!
