Other basic functions of dress include identifying the wearer (by providing information about sex, age, occupation, or other characteristics) and making the wearer appear more attractive. Although it is clear why such uses of dress developed and remain significant, it can often be difficult to determine how they are achieved. Some garments thought of as beautiful offer no protection whatsoever and may in fact even injure the wearer. Items that definitely identify one wearer can lose their meaning in another time and place.
