Starting in the second stage, players can change the appearance of their store by hiring the interior designer Michel. His services include rearranging the store's layout in three different ways and replacing one theme for another. New themes are unlocked as the story progresses. The third stage allows players to customize the interior by themselves, giving them full control over the store's visual presentation. But even with this level of freedom, there is still a limit to how many objects one can place.
Ergonomics play a role in maximizing profits and work efficiency within the store's boundaries. It is recommended to place rows of fitting rooms on one side and mirrors at another. There should also be enough space for other customers to explore freely especially if the player's brand is popular enough. Thus, cluttering the area with excessive displays may only hinder the flow of traffic, causing people to leave in frustration. While Mannequins are a good way to display several clothes at once while saving space, this should not discourage the use of shelves and racks since most visitors are likely to purchase a single item than an entire ensemble.
