1. A virtual fitting system, comprising: one or more processors; and a memory in communication with the one or more processors and storing instructions that, when executed by the one or more processors, are configured to cause the system to: store sizing data comprising a 3-dimensional target model of a target, the target comprising a room; receive, from a computing device, user input data indicative of a selection of a test object, the test object comprising a piece of furniture, the computing device comprising an augmented reality device worn by a user; receive, from the computing device, sizing data associated with the test object, the sizing data being acquired by sensors associated with the computing device; generate, based on the sizing data, a 3-dimensional test object model associated with the selected test object; apply the selected test object model to the target model to create a virtual fit model; and provide, to the computing device, the virtual fit model for display by an augmented reality display.
