Gorgeous floral shirt sz S ( 2-4 approx)

Beautiful colors! Floral button up long sleeve cotton shirt. It says L but it’s NOT. Please go by measurements only. I’d say it’s a size 2-4 ( small). Please know your measurements. It’s super cute with no flaws. Thin and ready for spring. Measurements are: under arms across chest 19”, across back shoulders, arm length is 25” and overall length is 28”. Comes from a smoke free pet home.
