Vintage sun dress

This cutie shows some wear but is such a fun piece with plenty of life left to give! Straps adjustable but safety pins were used to secure and pull in on the sides. Elastic is intact but is very stretched in waist. No size but would say a modern medium-large would fit best. All vintage items show signs of wear but I do my best to inspect and point out any flaws. Feel free to ask any questions- thanks for looking!!
