Vintage Embroidery Spring/Summer Dress

No tags, no size. Likely from 60’s/70’s. I bought it for a light shift dress but got pregnant and never wore it. The vintage store (bought on Queen st.) tag is still in it. I would say medium to large. The embroidery is so pretty and all over the dress. It is vintage so there is some wear at the bottom and some loose threads but all together it is in excellent shape otherwise.
