I purchased this beautiful vintage 1950s dress from a seller on Etsy. I believe its a rayon organza. The flowers are a raised almost velvet like texture. I would love to wear this dress for my upcoming wedding, but am a bit stumped on what undergarments would have been worn originally. The dress that I received is sheer and other than the original veil/headpiece and invitation nothing else was included. Wondering if anyone might have insights on what would be period appropriate for the base layer(s)?
