Abstract
The objectives of this study were to identify the dimensional structure of female impression formation based on silhouettes and necklines of wedding dresses, and to analyze the effect of silhouettes, necklines, and perceiver's gender on impression formation. The experimental design was 3$\times$6$\times$2 (silhouettes$\times$necklines$\times$gender) factorial design by 3 independent variables. Samples were 432 males and females. Four factors derived to account for the dimensions of impression formation. These were attractiveness, neatness, feminity, and prettiness. Dome silhouette had a positive effect on impression of attractiveness. Bell silhouette increased the impression of femininity and prettiness. Tubular silhouette had a negative effect on the impressions of attractiveness, femininity, and prettiness. Neckline had a significant effect on impression of attractiveness and negative on prettiness. Sweet-heart neckline has a positive effect on impression of attractiveness and negative on prettiness. Off-shoulder neckline increased the impression of prettiness. Round neckline decreased the impression of attractiveness. On the interaction effect according to the neckline and perceiver's gender, the men perceived high-necklines to be more feminine than did women, while the women perceived off-shoulder necklines to be more feminine than did men. There was interaction effect between silhouette and neckline on prettiness. In dome silhouette, heart-shape neckline was perceived to be prettier than the others, while in bell silhouette, off-shoulder neckline was perceived as prettier than the others.
