60s Vintage Yellow Cropped Blouse with Keyhole Neckline and Gold Braided Details

This is a gorgeous late 60s early 70s blouse. Made of a bright yellow synthetic fabric, the shirt has a cropped fit and long sleeves with a keyhole style neckline. The blouse has gold braided and sequined cord along the bottom and around the neckline. In good vintage condition with no major flaws to note. Has no size tags - Likely handmade. Measurements in line with a medium. I believe this was likely a part of a matching hostess set.
