Olive & Oak XS taupe blouse long sleeve front packets back pleat 2 materials

Olive & Oak XS taupe blouse long sleeve front packets back pleat 2 materials. 19 inches wide at chest, 24 1/2 long in front, 27 long in back. Seems more like a S or even medium with the width. 2 materials, see close up pic, for a pretty different detail. The top and collar feel like a Jersey material (rayon) and the main part of the shirt is polyester. The taupe is hard to show but it’s a true taupe, so neutral! Great shirt that goes from day to evening easily.
