There have been releases of this sort before, but I don’t remember anything like this:
The Vintage Patterns Wiki released 83,500 sewing patterns of pre-1992. You can find pretty much everything from the Dynasty-inspired suits and Betty Draper’s frocks and white gloves. There’s also an 1985 boys’ Reefer Suit and short trousers.
The search can be narrowed to particular pieces, designed and decades. There are patterns from the 1920s, 1930s, 1940s, 1950s, 1960s, 1970s and 1980s.
Lots of illustrations at the link.
