You might think that Christmas pajamas are a recent trend, but they've actually been around for over sixty years. Fashion historian Debbie Sessions notes that the tradition of wearing matching family Christmas pajamas dates back to 1957.
The trend even has earlier roots with the development of children's clothing styles. Jennifer Farley Gordon explains that this coordinated look was especially popular during a time when culture emphasized family and mother-daughter relationships. By the late 1950s, dads also joined in on the trend, making it a beloved family tradition.
