Who says the masks on our faces are our uniforms? No one.
When the pandemic was first on the news, there was a massive purchasing of masks, all sorts, especially the n95 masks... yet people weren't wearing them - until they got the signal from the news agencies and propagandists. Then "everyone play your part", and "we're all in this together". Follow the crowd, obey the TV. There were masks everywhere, like something completely coordinated.
When things calmed down the top google search became "mass formation psychosis" because of the people who were stunned by the number of people who joined in this hysteria by what they were TOLD.
I would say the MSM (although they are just the loudspeakers) are the ones who says the masks on our face is our uniform. A symbol of complete submission.
