I know I have a few 1950s black dresses, but you haven't seen this one.
It was $16.80. Yep, you heard it. From etsy store QsDaydream.
The brooch I got from a vintage store and I am not sure of the era.
My mother-in-law reckons '20s or '30s - I wouldn't be
interested if anyone else had an idea/guess.
