Consumer behaviour is a complicated and diverse area of study. Since marketing is based on identifying, anticipating and providing customer needs it is important to understand them. There are two predominant types of buying: consumer buying, which consists of buying products for personal use, and organisational buying, which involves buying for organisational purposes. For marketers to satisfy consumer needs more fully than competitors it is important to recognise the elements that influence buying. This report will identify the main factors influencing consumer behaviour patterns, particularly when purchasing fashion items. It will examine how buyer characteristics influence buyer behaviour and also how retailers react to such characteristics. In particular this report will look at the cultural factors, demographic factors and psychological factors that influence consumer buying
