Marines and Sailors cannot wear their uniform when participating in public speeches, demonstrations, assemblies, interviews, picket lines, marches, rallies, or any public demonstration which may imply service sanction for a cause that furthers “personal” or partisan views on political, “social,” economic or religious issues. So because the only reason listed in the thread is for personal display for their purpose, it is not supposed to be worn.
If they were going to wear the uniform to promote the corps, that could be cleared by probably not to so very young marines that would not be prepared with the experience or training to answer questions or make comments on military matters, theories, or current events that the marines have troops in those slots with the proper answers and comments. And they would be respresenting the Marines and not themselves.

Obviously, their public decorum must also appropriately reflect on the Marine Corps.
Don't you remember when all of the services encouraged the wearing of dress uniforms and - back then, the public was proud to have them in their uniforms?
