Equipment Yellow & Blue Floral Button Down Shirt (Sm/Med)

Perfect condition (never wore ). It's tagged a size small, however I considered it more of a medium when I bought it as the pit-to pit is 21 inches (unless you are a small that likes wearing shirts oversize). Last 2 pics are stock photos of the shirt. I was hoping I would lose an inch too fir it at the bust, but that hasn't happened so I decided to list it as I was clearing my closet!
