Vintage 70’s Peach dress with long pleated skirt and sheer arms size 10

Amazing dress! I’m not sure if it’s age but based on the brand and the collar I think it is correct. Also there is no size tag, but according to the measurements it should fit size 10. Flat lay bust across the front is 19”. Flat lay waist across is 15 1/2”. The zipper in the back from top of the collar until it’s end is 25 1/2”, we’ll below the hips for easy in and out. The skirt measures from the waist to the hemline 40 1/2” long. I don’t see any stains or damage. There is one button missing on a sleeve, so I am throwing in a pair of matching buttons for the replacements. Let me know if you need any more measurements!
