What type of rack is commonly round and used for displaying clothing?

The term "rounder" refers to a specific type of clothing display rack that is designed in a circular or round shape, making it ideal for showcasing a variety of garments in a compact space. This design allows retailers to maximize floor space while providing customers easy access to a broad selection of items. Rounders are particularly effective in retail environments because they can hold many items at eye level, making it visually appealing and encouraging shoppers to browse.

Other options do not accurately describe the type of display in question. A hanger is typically designed for individual items and is not a rack, while a mannequin serves to present clothing on a life-sized model but is not a rack itself. Rack display is a more general term that does not specifically denote the round shape that characterizes a rounder. Therefore, the specificity and functionality of a rounder make it the appropriate choice for this question.
