The purposes of this study were to clarify : 1) the flaring effect of skirts on silhouettes by using different lengths of hem-line (that is, waist size remains constant while hem-lines vary from 3 times to 6 times the waist size respectively); 2) what types of flared skirts were favored from data in the sensory evaluation procedure. The skirts were produced by three kind of fabrics. The results obtained were as follows : 1) As the length of the hem-line of the flare was increased, the length of the side line tended to increase also, while the length of the center line increased when the hem-line length was up to 4 times the waist size and came to a constant value after that length; 2) The wave-height also showed a tendency to increase when the hem-line length was up to 4 times the waist size. The minimum values of the variation ratio of wave-height varied from each other according to the different types of fabrics; 3) The sensory evaluation showed that the shorter hemline was not favored. The most favorable length for the hem-line was not found because different types of fabrics produced different favored hem-line lengths.
