This study attempted natural dyeing Hanbok design by applying formative elements of traditional Korean costume based on costume contents. Among the roots of the peonies with various medicinal effects, red peony, with relatively excellent dyeability compared to white peony, was selected as the dyeing material. Dyeing was performed using a complex red peony and gardenia extract to develope a fashion product with color development. A quilted Baeja was made using dyed silk fabric, and the results are as follows. The silk fabric dyed with the red peony extract was yellow-red. The silk fabric was dyed with red peony extract, and the gardenia extract was yellow. All of the silk fabrics dyed with the red peony extract alone, and the silk fabrics dyed with the red peony extract and the gardenia extract, were all excellent in color fastness except for the daylight fastness. In the case of silk fabrics dyed with red peony and gardenia extracts combined, the ultraviolet blocking function was slightly improved compared to silk fabrics dyed only with red peony extract alone. In addition, four pieces of quilted Baeja were produced by quilted silk dyed with a complex extract of red peony and gardenia with a sewing machine at 1cm intervals, using this as the outer fabric and using white silk as the lining. It is produced in a round-edged collar, angular-edged collar, and collarless and a slightly shorter or longer form. The quilted Baeja excavated from the Joseon Dynasty was used as a cultural archetype of costume. This fashion product is expected to be a fashion product with aesthetics as a method of psychotherapy that can be combined with medication therapy.
