1970s calico cornflower blue dress above knee back to school on the prairie

This prairie style cottagecore dress is beautiful on and a true beauty —it’s long sleeve with gorgeous embroidery on the square collar. Dates back to at least the 1970s possibly late 1960s. Reminds me of well dressed wolf. My iron is out but the details around the collar are gorgeous. A true gem. Tag says 6x but check measurements bc this is a vintage dress… that’s at least 50 years old.
