Clothing serves both practical and abstract purposes. It provides protection, modesty, communication of individuality and social roles. Fashion is largely a western concept based on ideas of consumption, status, and identity. People negotiate their place in social groups and as individuals through their clothing choices. Clothing can be either fixed, changing slowly over time and place, or modish, with rapidly changing styles associated with western cultures. Ideologies like Marxism see fashion as perpetuated by industry to support consumerism and capitalism.
