This study examined the functional comfort and perceived acceptability of selfdeformable knit skirts using Nitinol modules. Four skirts were prepared by combining two silhouettes, straight and flare, with two levels of distributed module density, four modules and six modules. Ten women participated in a repeated-measures evaluation in which all four garments were worn and assessed. Functional comfort was measured for each skirt in terms of mobility, thermal comfort, tactile comfort, donning, alignment usability, shape stability, and overall satisfaction. Perceived acceptability based on the WEAR framework was assessed after participants tried both the four-module and the six-module skirts. The flared skirt with six modules received the highest mean score for overall functional comfort, whereas the straight skirt with six modules had the highest mobility score. Shape stability differed significantly, with the flared six-module skirt receiving the highest scores. In contrast, tactile comfort remained relatively low across all garments, and open-ended responses identified prickling sensations, stiffness at the connection area, and the need for better lining or finishing as major areas of discomfort. There was no significant difference in WEAR-based perceived acceptability between the four-module or six-module skirts, suggesting that functional comfort and product acceptability did not vary. These findings indicate that the effect of module density should not be interpreted linearly and that the development of self-deformable skirts depends not only on actuation performance but also on finishing quality, alignment usability, tactile comfort, and balanced integration into wearable garments.
