Vintage 70s yellow lace trim maxi boho dress

This is a vintage 1970s canary yellow prairie dress The color of the dress is like the first three photos. Lighting is off in the last few ones. Great condition. Small spots but nothing noticeable. Has been soaked and washed. The dress has a zip back, but no stretch. I’m thinking this dress fits a small individual. No size tag was found, so please measure. Measurements laying flat: Armpit to armpit:16” Shoulder to hem: 53” Waist: 14” Hips: 15”
