This study intends to analyze the fit of directly-imported American casual pants for Korean female college students in terms of appearance and comfortableness. The authors carried out a wearing test with sample pants from 3 brands (DKNY: A, Gap: B, Pol C) that had the most market share and that were mostly preferred by Korean female college students. Results showed that pants A had insufficient ease in the crotch, as the depth of the crotch was short. The hip girth received a low assessment in terms of appearance. Moreover, the hem widths were wide while the pants length was long. Pants B were expected to be most appropriate for Korean women’s bodies, as they had the longest crotch depth among the three brands. However, the pants appeared to pull downward due to the narrow thigh and the knee girth and hem width. Moreover, the crotch girth and hip girth received a poor appearance assessment. Pants C were rated as satisfactory for their thigh girth, knee girth, and hem width. However, the crotch was uncomfortable, as it had a short crotch depth. The hip girth received a low appearance assessment. This study suggests that a pattern adjustment is required for directly-imported American pants to provide a better fit for the bodies of Korean women. The crotch depths should be approximately 17.5 cm. The hem widths should be approximately 20 cm. We also suggest a leg length of 75 cm, a waist girth of 86 cm, and a hip girth of 97 cm.
