This paper conceptualizes clothing fit and represents fit attributes in detail using Logic statements with either common logic symbols or uniquely defined symbols to indicate thought process and then expand to the implemented level of Fit. These Logic statements explain the relationships between body and fit in 3D and 2D along with 1D and 0D features and measures. This work introduces four assets: Human, Humanoid, Cover, and Coveroid; and the fit attributes depict the relationships of those assets. Subsequently, 16 transforms are combined to broadly define technology offerings involving physical and virtual fit. Importantly, the Logic statements are shown to depict proposed relationships that determine Intended Fit and Expected Fit. Fit statements were expressed for both known and unknown parameters; therefore, it can simulate a Ready-to-Wear Use Case, and Bespoke to Made-to-Measure Use Cases. In addition, 2D and 3D fit landmarks are described in the form of geometric details, including body geometries and measurement locations for known and unknown Humans and Humanoids. This work has characterized the essential parameters of Design Realm, Production process impact, and underneath cover(s). The Design Realm has incorporated: Universal style tag requirements, Emotive Design, and Human shape-dependent parameters. Since the fit is impacted by time, 4D concepts can be incorporated into a virtual avatar, in which Planned Fit is described by Rigging. This work translates all the fit principles used in the apparel industry into logical statements for both mathematicians and digital tool developers. Consequently, this will augment software intended to automate Cover design and development.
