The apparel industry relies on subjective traditional fit measures of expert analysis and subject responses and objective body dimension measurements to quantify the fit and size of garment prototypes. In this study, an objective method for the analysis of fit is validated by comparison with traditional measures. Assessment of apparel fit for all measures focuses on the effect of postural differences and garment fit for mature women between the ages of 55 and 65. The objective method uses slashed garments and image analysis tools. Results of the analysis of high contrast video-captured images of subjects dressed in test jackets are compared to traditional fit measures. Expert analysts and the image analysis method developed for this study are both capable of defining the complex interactions of the garment/body interface.
