Vintage 1940s black lace strapless dress

Vintage 1940s black lace strapless dress with removable lace “half jacket/top sleeves” also comes with a belt. In beautiful condition. No size indicated, looks to be probably a 12-13. Has black lace and black sheer material underneath. Dress flairs out towards the bottom. Was worn by my mother many years ago and has been well cared for in a dress bag. I have a photo of her in dress somewhere, will try to locate.
