This study analyzes the visual image effects regarding the design changes of sleeves and shoulders on plus-size women in their 20s and 30s to propose ideas for plus-size women’s clothing production and design. Based on a plus-size women’s basic raglan sleeve shirt, six types of raglan sleeve shirts with various design elements were developed using a 3D virtual imaging program to analyze the visual image effect of each pattern’s features. The results showed that the A-shaped sleeve silhouette, exemplified by Pattern A2, makes the upper body look longer and slimmer as a whole. It also conveyed a sense of refinement and attractiveness, displaying positive effects regarding body shape and aesthetic perception. Meanwhile, O-shaped silhouettes, such as Pattern B1 and Pattern B2, showed positive effects regarding comfort and mobility, while Y-shaped silhouettes, such as Pattern C1 and Pattern C2, created a visually confident appearance. Furthermore, the research examined the effects of static images and dynamic videos on evaluation outcomes. The results showed that dynamic images enhanced immersion and vibrancy, thereby increasing focus on the apparel evaluated. The results of the visual image evaluation can be used as a basis for designing not only raglan sleeves but also overall sleeve shapes.

The purpose of this study is to evaluate the differences of body compensation image on variations in the shoulder height and width of power shoulder raglan sleeve jacket. Nine samples were examined: 3 variations of the shoulder height and 3 variations of the shoulder width. The data was evaluated by 123 fashion design majors. The results were as follows; as a result of analyzing the body compensation image according to changes in the shoulder height and width of power shoulder raglan sleeve jacket, five factors were selected; the shoulder compensation factor, the bust compensation factor, the waist compensation factor, the arm compensation factor and the neck compensation factor. Among these factors, the shoulder compensation factor is the most important factor. Examining the major effect of the body compensation image based on changes in the shoulder height and width of power shoulder raglan sleeve jacket, it had an independent influence on factors about waist, neck, shoulder and arm compensation except a factor about bust compensation, had an influence on interacting effect of factors about shoulder, bust, waist, arm compensation, and it had no influence on interacting effect of a factor about neck compensation. This shows that the shoulder height has larger effect on neck compensation image than the shoulder width in power shoulder raglan sleeve jacket.
