Cato denim shirt. Xl long sleeve light wash. GUC

Women’s xl button up denim shirt long sleeves. Light blue denim color. Very cute on. Noticed it has a round circle on the back of the shirt that’s outlined right below shoulder seem. Very small place. I never noticed this before so I’m not sure what caused it or if I bought this way new. See pics. Doesn’t effect the look of shirt. Needs a good iron or steaming and would look great. I just don’t have time to iron everything I sell. Pet friendly home.
