I often get questions on this blog about where to buy vintage 1920s, or how to buy it in larger sizes. The above dress is for sale with one of my favorite dealers, Dorothea’s Closet (more photos at the link). It’s $310 which is an excellent price for a vintage 1920s dress like this in a generous size, and she does layaways so you can pay in installments.
Here’s the information from the site:
"Art deco design black sheer silk 1920s evening dress with blue and silver beading. Snaps at shoulders, no other openings. A few tiny holes, no shattering..sturdy and wearable. The waist appears to have been taken up, leaving as is. A few missing beads but does not affect the deco design."
The measurements are generous: 48” bust, 44” waist, 56” hips, 46” long
With a dress this sheer, you could try different coloured slips underneath to get different effects.
