Dynamite Button down blouse smoke grey size M long sleeves very light

Pretty blouse worn mostly to the office. Color is smokeish blueish grayish, for the lack of a better description. Really cute with a black skirt or pants. GUC, a bit of a thread pulling on the right side, can't really see, priced accordingly. I tried to take best photos as I could. Measurements: Length from decolt approx 43 cm Shoulders approx 42 cm Width at waist approx 56 cm
