A vintage long sleeved dress with kick pleats

This dress is a beautiful sapphire color. My best guess is this dress is likely circa 1975. It’s unbranded, union made, and originally marked a size 12. In modern sizing, I believe it is closer to a modern 16/18. The waist cinches in to sculpt the shape of the wearer and while the sleeves are sheer, the dress does have some weight to it but also manages to have stretch. 🐱Cat loving, non-smoking home! 🐱 Shoulders: 43 Bust: 43 Waist: 46 Hip: free, up to 56 Sleeve: 21 Length: 39
