Cute vintage 70’s striped button down top blouse

Nice bright colourful vintage top. Tag says size 20. It’s missing at least one button on the bottom and has a small loop at the top collar that doesn’t have a button either. I’m unsure if there was one originally. Some stitching is slightly coming away. lightweight soft silk like polyester material. Easy to find replacement buttons to be like new. Has one small pull that I have pictured. Measures approx. 26” in total length. 23.5” pit to pit. Please see photos for the best description. Thank you.
