Refer to the following scenario to answer the following question$($s$).$

Kamesha's Clothes is a retail clothing store that is considering expansion into nearby communities. Kamesha started her store four years ago and has done well focusing on providing stylish clothing to middle$-$income buyers. However, before she expands she would like to understand her customers better and see if she can expand her appeal to other demographic groups. During her last buying trip, she added some more expensive items to her inventory. However, very few of the added items have been sold. Kamesha is trying to decide whether to begin marketing the items more aggressively or whether to focus on other groups.

What value proposition made Kamesha's business successful and how can she build on that success?
