Hello All! Can anyone help me with this dress as I am really not sure how to date it. Its very slim and 'wiggle dress' shaped, though button through, and has large cut outs at the back. At first I thought 80's, though the label itself looks older I think. I'm also not sure what the fabric is - it has a slightly silky look and feel but I think it is a synthetic of some kind as some threads from it melted into hard black blobs when I did a burn test on it (my first!!). The label says Hand Wash Drip Dry Warm Iron - which has confused me further as I thought that most of the synthetics were machine washable ... but maybe not! The buttons look metallic but are plastic. Any thoughts appreciated!
