COPY - Vintage 50’s Party Dress, tea length

Vintage, 1950s! I bought this dress at a thrift store over a decade ago- union made in the USA, illusion sweetheart neckline with sheer polka dot overdress. I am suspicious this could be an 80s repro, as the fabric is still a consistent white- not faded or yellowed at all & brand label is a bit modern. No petticoat, but could use one for added poof. This would be great for true vintage fan, prom, or very casual wedding! Measurements available upon request- a small 8 or large 6 in modern sizing.
