The Power of Postal Uniforms

One of the more rewarding benefits of working on the “Mailin’ It” podcast is that I get to have serious (well, semi-serious) conversations with lots of interesting people who have direct impact on the Postal Service’s connection with the American public and our culture.

A perfect example of this is a recent episode my colleague, Yasmine Di Giulio, and I had with Alison Bazylinski, Assistant Curator at Smithsonian’s National Postal Museum.

Alison broke down for us how the iconic blue and ‘cadet grey’ Postal Service uniform came to life and how it became synonymous with the Postal Service’s reputation for integrity, professionalism, and commitment to public service. Alison also gave us insight into how society shaped our uniform’s evolution from its semi-military origins to today’s more casual, and practical, outfit.

Our “Mailin’ It” podcast with Alison is one you should not miss. And, to help you along, here are archival photographs you can use to visualize Alison’s descriptions.

You can also find out more about Postal Service uniforms, as well as USPS’s singular bond with the American public, at the Smithsonian’s National Postal Museum.

Iconic blue and cadet grey uniform

The iconic blue and cadet grey uniform was introduced in 1868. The first uniforms, as seen in this photograph from 1888, mirrored the men’s business dress fashion of the day. With no access to mass production or standard sizing, early uniforms were made by local tailors guided by instructions provided by the Postmaster General. Collection of USPS.

In 1899, the Post Office Department authorized the use of stars on a letter carrier’s coat sleeve to recognize long service. Different colors and numbers of stars could be added to recognize 5 to 40 years’ service, in increments of five years. By the late 1950s, 50 years’ service could also be commemorated.
