Baseball caps have different functions such as sunshade, decoration, warming and protection. Therefore, there are many types, and the choices are also particular.
The human face is mainly composed of a square type (national character face), a round type (round face), and a pointed type (sharp face). Wearing a round cap on the round face, it looks big and the hat is small. Such as wearing a wide cap is more appropriate. The sharp-faced person wears a cap and appears to be bigger and smaller on the face, and more slim. Therefore, wearing a dome cap is more appropriate. People with Chinese characters wear all the hats.
A baseball cap that is taller should not be worn too small, otherwise it will give people a light and heavy feeling. The short person is the opposite. A tall woman should not wear a high baseball cap, otherwise the feeling is "again". A short lady should not wear a flat-topped baseball cap and it will look shorter.
