Fashion psychology, as a branch of applied psychology, applies psychological theories and principles to understand and explain the relationship between fashion and human behavior, including how fashion affects emotions, self-esteem, and identity. It also examines how fashion choices are influenced by factors such as culture, social norms, personal values, and individual differences. Fashion psychologists may use their knowledge and skills to advise individuals, organizations, or the fashion industry on a variety of issues, including consumer behavior, marketing strategies, design, and sustainability.
