Beautiful 1970s union made Sears green and white dress

Vintage 70s union made green and white dress. Brand is Sears fashion place. Honestly, don’t believe this dress has ever been worn. In perfect condition. Vibrant Kelly green skirt matched fun button detail on the shoulder. Elastic waistband. Size marked 12 but fits like a 2-4. So torn about selling this Measurements: Bust: 15” Waist: 12 1/2” Length: 40”
