I have some pages dedicated to clothing available in the UK for women: 1920s women’s , 1930s women’s, 1940s women’s, 1950s women’s, and 1960s women’s, and for men’s (20s-70s) here.
For Australia/ NZ shoppers I have this page for all decades (mostly women’s). Many of these items are included in all other shopping pages and many stores ship internationally. Look at the price to see the currency in your country. Outside of the USA, Canada and UK my resources and knowledge are limited.
