short-sleeve pinafore crew-neck dress, vintage late 1970s-1980s, made in Canada

Cute dress with front pinafore, ala "Lady Diana". Crew neck, short sleeves. Polyester boucle material. Another one of my aunt's from late 1970s-early 1980s. It is also made in Canada. These were "dresses bought from major department stores back when Canada had a domestic garment manufacturing industry. Shoulders are approximately 15" wide (i.e., as measured flat, and not including the width of the pleated sleeves). Made for a smaller bodice. 41" from nape to bottom hem. Fits a women's US size 4-6. Excellent condition. No damage.
