The choice of dress which corresponds to aims and needs or the influence of clothes on human behaviour, constitute interesting examples of interrelationships between the individual and the environment. Attention is focused on the case of dress chosen in order to confer sociaiprestige and on dress which confer the reverse. Subjects of both sexes, young and to mature, of average social class, were examined. The two opposing sets of clothing show special characteristics and the functional significance of these was explored. Change in the clothes produces clear-cut effects on certain aspects of one's self-image, while other aspects are unalterated. The structure of the personality and environmental demands can increase or reduce these clothing effects.
