An Alternative Approach to Sizing Apparel for Women 55 and Older

Abstract

The purpose of this study was to examine Principal Component Sizing System (PCSS) methodology as an alternative approach to advancing the mathematical efficiency and effectiveness of apparel sizing for women 55 and older (Salusso-Deonier, 1982). The 1994 American Societyfor Testing and Materials (ASTM) national body measurement databasefor Women 55 and Older was classified using the PCSS method (ASTM, 2001). PCSS-55+ has a thickness-by-length structure similar to the current domestic sizing system. Only 25 sizes were needed to encompass the same range as compared to the 55 sizes within the current sizing standard. The PCSS method correctly classified 95% of subjects within 25 size categories and demonstrates potential as an alternative methodfor creating a simplified and marketable apparel sizing systems. With appropriate methods and databases, revision of US. apparel sizingfor women of all ages can provide long awaited valid and reliable sizing.
