Vintage Peplum dress

Clearing our my vintage items that I no longer wear or can't wear anymore. This is a dress that I wore to a wedding one time back in the late 80's or early 90's. It has been in storage ever since. Tag says it was made in California, so you know it's older. Beautiful peachy pink color. I have no idea about what materials it's made of, but it's satiny and very lightweight. My guess is that it's poly-satin and that you would need to dry clean only for care. Buttons on back are mother of pearl like, and the rouching at waist is fixed on the sides, with a lining on the inside and the center is flexible. Top of sleeves are slightly capped. No buttons on wrists. Kick pleat on back of skirt. No rips, tears, or stains. Last pic is a closeup to see that the slubbing is made into the material on purpose. Smoke-free pet free home. Measurements are apprx; 18in bust 12in waist (at smallest) 14in hip 24in sleeve 7in kick pleat length 40 1/2in overall length from top to hem
