Final answer:
Monopolistically competitive retailers include department stores and the variety found in malls; Ann Taylor, Banana Republic, and Victoria's Secret are examples.
Step-by-step explanation:
An example of a monopolistically competitive retailer can be seen in the ubiquitous presence of department stores and the large diversity of stores within a shopping mall like the Mall of America. In such environments, numerous firms compete against each other with products that are not identical, offering different styles, brands, and consumer experiences. These retail establishments, such as Ann Taylor, Banana Republic, and Victoria's Secret, exemplify monopolistic competition by providing distinctive clothing options and establishing mini-monopolies based on their unique brand perceptions.
