Vintage 70s Small? Wedding Ivory Polka Dot Embroidered Floral Dress Boho Prairie

Vintage 70s Small? Wedding Ivory Polka Dot Embroidered Floral Dress Boho Prairie Excellent condition aside from some small spots on belt (pictured) that I haven’t tried to remove and some visible stitching at back zip! No inner tags at all so I’m estimating it to be a modern size small! Please check measurements below carefully! This piece may be older than the 1970s that I’ve estimated; I’m just unfamiliar with clothing older than the 1950s! Measurements: Armpit to armpit: 17” Sleeves: 13.5” Waist: 14” Length: 55” Themoderngirl
