This study suggests designs of maternity clothes wearable after childbirth and aims at confirming that maternity wear is continuously wearable during a post-natal period. As for research methods, theoretical and empirical studies with research on a production of work were conducted, focusing on the design development of the maternity dress which may be worn even after childbirth. The results of theoretical and empirical studies possibly presented various designs which require fashionability going with the trend of time. The maternity wear also requires the adaptability for a changing body shape to enable a woman to wear it during a pregnancy period and after childbirth. Besides, the convenience of dressing and undressing with wearing comfort is considered. 6 sets of one-piece dress were made as the result of the study and three factors of fashionability, adaptability and convenience were considered. The conclusions are as follows : Firstly, it verified that the maternity wear is fashionable clothes not to cover protruded abdomen but to satisfy women's desire of self expression. Secondly, it overcame the limit of dress design through fitting it to completely different two body sizes and shapes with design factors and patterns. Lastly, it suggested a research model of maternity wear corresponding to economical, environmental and ethical principles as giving an effect of “two” dresses with one. This study presented a new direction of design study with meaningful actions of fashion designing in the aspects of economical, environmental and ethical consumption unlike artificial disposal on SPA brands.

The knitting method of the sleeves for improving movement adaptability were studied in this paper. The purpose of this study is proposing a knitting method that is suitable for the bodies of women in their 20's and can enhance wearing satisfaction. To see the effect of the bind-off length at the axilla, a movement adaptability test was undertaken for 4 samples that have bind-off at bodices. In addition to that, the analysis of their sliding distance with respect to the human motions were executed. The results of this study were listed below. Its result was that the samples with small bind-off lengths represent better wearing satisfaction than the samples which have large bind-off lengths. The comparison of the sliding distances at the hem, waist and sleeves with respect to the tester's motions also shows that the sample having small bind-off makes better result than the sample with large bind-off. It was observed that the optimal length of bind-off was 2cm for the improvement of the sleeve functionality.

The purpose of this study is proposing a knitting method that is suitable for the bodies of women in their 20's and can enhance aesthetic aspect and wearing satisfaction. For this study, four kinds of seamless knit one-pieces were implemented by different knitting method of waist dart each other. The inspection of the exterior and the sensory test of movement adaptability were included in this study. The results of this study were listed below. Exterior evaluation of the four samples results that the sample with outside narrowing and widening get low grade. Thus, we can see that the method having only outside narrowing and widening for waist shaping can cause problems. In addition to that, the sample with inside narrowing and widening get highest grade for almost all test items. The dressing evaluation results that the knitting method of waist dart affect only on the exterior but not on the movement adaptability of the seamless knit one-piece.
