What is one of the key benefits of using mannequins in retail displays?

Using mannequins in retail displays is particularly effective because they visually showcase complete outfits, making it easier for customers to envision how clothing items can be styled together. This method of presentation can attract customers' attention and inspire them to make purchases, as it highlights the versatility and appeal of different garments. Mannequins serve as a visual cue that helps to communicate trends and styling ideas, which can enhance the shopping experience and increase sales.

The other options, while they may have some relevance to retail operations, do not capture the primary advantage of mannequins. They don't inherently reduce inventory needs, provide product information, or increase storage space in a meaningful way compared to the benefit of creating engaging and appealing visual displays that attract customer interest.
