McCall's 5805 Voluptuous Dress with Two Skirts 1961 - this unused pattern is so rare. I suspect that everyone who bought it used the bat snot out of it and wore them out. It's not even on the pattern wikia.
Had a customer write me the other day asking if I had a man's "Hollywood" jacket pattern. Not the maker but the style. Here is what she was looking for. She was from the UK and referred me to Heyday! Vintage Style Clothing which was fun to go through.
