In the retail industry, a buyer is an individual who selects what items will be stocked in a store, based on his or her predictions about what will be popular with shoppers. Retail buyers usually work closely with designers and their designated sales representatives and attend trade fairs, wholesale showrooms and fashion shows to observe trends. They may work for large department stores, chain stores or smaller boutiques. For smaller independent stores, a buyer may participate in sales as well as promotion, whereas in a major fashion store there may be different levels of seniority such as trainee buyers, assistant buyers, senior buyers and buying managers, and buying directors. Decisions about what to stock can greatly affect fashion businesses.
