The purpose of this study is to evaluate aesthetic appearance of flared skirts in dynamic state objectively. We studied the relationship between subjective values obtained from sensory test of moving skirts' appearance and mechanical parameters, shear and bending vibrational properties of those fabrics. We selected mechanical and vibrational parameters for an objective evaluation equation of beautiful appearance of moving flared skirts by cluster analysis of those mechanical and vibrational parameters. By using those parameters obtained from cluster analysis, the equation to describe aesthetic appearance of moving flared skirts objectively was derived for "flowing", "rhythmical", "blowy" and "beautiful" one. The total beautiful appearance of flared skirts in dynamic state was evaluated mainly by flowing and rhythmical moving subjectively. The compound mechanical parameters such as (3)rootB/W, root2HB/W, (3)rootG/W and static drape coefficient explaining static silhouettes of flared skirts showed good correlation with "flowing", "rhythmical" and "beautiful" moving of flared skirts. Therefore those parameters might influence dynamic silhouettes of flared skirts.
