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 (pointed face). Wearing a round cap on the round face, it looks like a big face and a small hat. Such as wearing a wide cap is more appropriate. A sharp-faced person wearing a cap makes the face appear big and small, and is even thinner. Therefore, wearing a dome cap is more appropriate. People with Chinese characters wear all the hats.
The height of the baseball cap should not be 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.
