Can you tell me about the different kinds of hats and how they are worn?

Hats can be divided into two categories: headwear and protective headgear. Headwear includes things like baseball caps, newsboy caps, beanies, and other types of caps that cover your head. Protective headgear is used to protect your head from injury or harsh weather conditions, such as helmets for sports, hardhats for construction work, and motorcycle helmets.
