I want to know the answer to the following question:
What is the most popular head dress worn?
All the background I'm provided with is that "The beret is probably the most widely worn headgear and is worn with almost all orders of dress (with the exception of the more formal orders of Navy and Air Force dress), and the colour of which is determined by the wearer's environment, branch, or mission.". Is that enough to answer the question?
Answer: yes
