Human have covered their heads since evolution. Initially headwear offered protection from the elements, from injury or from falling rocks, weapons or masonry. Later head coverings became symbols of status of authority or of uniform and as time progressed they became an art form as well as an everyday piece of apparel.

In fashion terms hats are a very noticeable accessory because the onlooker's attention is alsways first drawn to the face. A hat is the most noticeable fashion item anyone can wear. The old saying goes 'if you want to get ahead and get noticed then get a hat'. Indedd the word ahead means just that one head further forward.
