Purple collared plaid sleeveless button down top

Purple collared plaid sleeveless button down shirt. Brand is St. John's Bay. Marked a size petite large in women's. Does look like it runs a little smaller, please check measurements to make sure it fits! 100% cotton material. Super cute! I could imagine this worn with denim shorts and the bottom part knotted up to make it more cropped or even tucked into some brown bottoms and paired with some cute sandals. Measures 18 inches wide (36 inches) by 20 inches long. Please compare measurements to your own to make sure it fits. Used item, has been washed.
