Stunning Vintage Dress

This gorgeous dress is from the 1960s or 1970s and is in near-perfect condition. There’s no tag but I’d say it’s about a size 4 (that’s the size I was when I bought it). As you can see in the photos, there’s a tiny lapse in the stitching under the arm if you lift it up but this would be very easily mended. Purchased from a vintage boutique in Alameda, CA. There’s a little stretch to the fabric- it may be a polyester blend. Has a lovely tie with a mother of pearl-like clasp.
