Covington Black & White Floral Sunburst Blouse

Very cute button down short sleeved blouse with floral/sunburst fabric design. It is from the brand Covington, but it looks like one of the tags has been cut off as I can't find what the material and size is. My guess would be a M/L, please see measurements. Measurements: Length 61cm, shoulder 44.5cm, chest 57cm, waist 49cm
