Abstract
With new 3D plus size body scan data available through surveys like Size North America and
manufacturers investing in their own data, there was an opportunity to study the shape of modern
female plus sized bodies to inform the fit of products for this emerging business demographic. The
researchers partnered with a leading apparel company to analyze 3D plus size body scans with the
Female Figure Identification Technique (FFIT) for apparel developed by Simmons, Istook, and
Devarajan (2004), using mathematical representations of the FFIT body shapes created by Lee, Istook,
Nam, and Park (2007). However, during the project, it was discovered through visual inspections there
were opportunities to modify the FFIT mathematical formulas to be more inclusive of plus size women.
The inspections indicated that some scans were inaccurately classified or not sorted into any shape
category. Since plus size women often have larger abdomens than bust or hips, the formulas were
modified to include a check for that condition. By understanding shape, manufacturers can have a better
idea of how to design, fit and grade products for this market throughout a size range, as opposed to
relying on only 2D measurements or linear grading rules from a sample size.
