Wearing American flag apparel actually violates a set of guidelines called the US Flag Code.
The fashion industry thrives on reproducing symbols and designs, and the American flag — like flags of all nations — is certainly a powerful symbol that can communicate messages of politics, patriotism, and pride.
But in 1942, the US Flag Code was established to set guidelines about how the US flag should be displayed and used. According to Smithsonian Magazine, the US Flag Code originated from a fear of addressing the national flag in a way that was reminiscent of the Nazis. One of the guidelines is: "The flag should never be used as wearing apparel, bedding, or drapery."
The code, however, is unenforceable. According to the United States Senate Committee on the Judiciary, "the Flag Code does not prescribe any penalties for non-compliance nor does it include enforcement provisions."
