Baeksubaekbokdo(百壽百福圖) is an artwork depicting 100 characters for 'Su(壽)' and 'Bok(福)' to wish for longevity and fortune. This study aimed to develop a one-piece dress design for infants reconstructed with textile patterns developed using the Baeksubaekbokdo'siconography, such as peach, pot, plum, turtle, and cloud. This study intended to enhance infants of positive and desirable personalities, such as physical growth and development, psychological stability, self-expansion, and aspirations for infants' health and happiness, and to familiarize infants with the value of traditional cultural archetypes, including Baeksubaekdo. In addition, it is to identify the value and excellence of traditional cultural archetypes and materials that can be used for practical commercialization. This study modified and supplemented the color, motif size, and repetitive arrangement method so that the textile pattern for infants developed in previous research could be applied to a one-piece dress design, an item preferred by infants. Five one-piece dress designs with a neat and refined image and a cute and lively princess-like image were developed. A survey was conducted by presenting 125 2D designs due to the convergence of 5 modified and supplemented textile patterns and five one-piece dress designs. The top three highly preferred one-piece dress designs were selected. The final three one-piece dress designs were produced and presented using a 3D virtual clothing program. Adobe CC (Photoshop2022, Illustrator2022) and CLO7.1 were used as production tools for textile pattern design, infant one-piece dress design development, and 3D simulation. In conclusion, this study suggested applying one-piece dress designs for infants with textile patterns of cute, lovable, and fun images developed using the iconography of Baeksubaekbokdo, which means longevity and good fortune. In addition, it was reconfirmed that it is a material that can be used practically for the value and value of a traditional cultural archetype and the health and happiness of infants and young children.
