Vintage 60s Victor Costa Romántica a line dress tiger stripe metallic mod

60s mod party dress by Romántica Victor Costa. Jewel neckline and a-line cut, with cute pockets in front. The fabric is on the heavy side, likely polyester lined with acetate. There are metallic Tiger-like stripes all over that give the fabric a textured look. Ivory color seems somewhat aged, and there is a yellowish stain at the neckline. I have never tried to clean it. Structurally good shape, with no rips, holes, or seam splits. 17” armpit to armpit 36” length
