17．Most of the time，people wear hats to protect themselves from harsh weather conditions．Hats are also worn to show politeness and as signs of social position．But nowadays，hats，especially women's hats，are much more than that．More exactly，hats have changed into fashion and style symbols by many movie stars．What's more，people now consider many different features （特点）when choosing even a simple hat．Many designers point out that，when choosing the right hat，it's important to consider the color of your skin as well as your hair，your height，and the shape of your face．
First of all，the color of the hat should match the color of your skin and hair．For instance，black hats should be avoided if you are dark skinned．If a purple hat is placed on top of red hair，one will look as attractive as a summer flower．Second，the height of the hat is also an important point．Tall women should not go for hats with tall crowns，just as short women should choose hats with upturned brims to give the look of height．Third，and most importantly，the shape of the face decides the kind of hat one should pick．A small，gentle hat that fits the head looks good on a small face．However，women with big，round faces should choose a different style．
As the saying goes，"Fine feathers make fine birds．"A good hat can not only help your dress but also support your features，so why not choose the best possible one next time you want to be in public？
