Vintage, Black William Pearson Lace Dress Size 12 Runs Small

This piece is in great condition! Please see all photos, as I have taken from bottom to top and all inclusive. It is lace, embroidery and satin edges and has a built-in slip. It can look like a two piece outfit, though it is a one piece dress. The only parts that are slightly see-through are the arms’ lace. It zips up in the back. It runs smaller than a size 12, an 8/10.
