dress code

A dress code is a set of rules, often written, with regard to what clothing groups of people must wear. Dress codes are created out of social perceptions and norms, and vary based on purpose, circumstances, and occasions. Different societies and cultures are likely to have different dress codes, Western dress codes being a prominent example.
Dress codes are symbolic indications of different social ideas, including social class, cultural identity, attitude towards comfort, tradition, and political or religious affiliations. Dress code also allows individuals to read others' behavior as good, or bad by the way they express themselves with their choice of apparel.
