Vintage Women's Short Sleeve Blouse Christie & Jill Size Medium Blue Geometric

Good used condition vintage button up blouse. Collared neckline. Size medium. 100% polyester. No stains or holes. There is the remnants of an iron on name tag to the inside back under the brand tag; this is not noticeable from the outside. I have included measurements in the photos. Lot #4107. I am guessing this to be from the 70’s as my research shows that Lot #s were discontinued around 1979.
