Today's pattern of the day is the super-rare Originator 383 being sold by ErikaWithaK Vintage.
If you don't know much about originator patterns, there's a really good reason these little gems are so hard to find. They weren't really mass-produced like Advance, Butterick, McCall's, Simplicity and Vogue were.
Originator only started out as a sort of "trade only" fashion news service. They provided subscribers like seamstresses and designers with current fashion sketches. It wasn't until the late 1940's that they started offering patterns to go along with their designs. Look at the price tag: $1.50 in the early 1950's. An advance pattern at the same time sold for $0.35. Not everyone could afford them, and even fewer had the skill to sew them.
