NWOT - Susan Graver sleeveless linen/cotton orange button-down blouse, size 8 This very summer & comfy blouse has pretty brown buttons down the front & two front pockets w/buttons, a rounded hemline & large side slits. I feel like this blouse runs big. I am an XL & it fits me, but is snug around the bust. Pit to pit is 20" & the length is 26".
