The purpose of this study is to analyze how modern fashion brands practice cultural sustainability by investigating the ways they use and reinterpret traditional culture and clothing. The transmission and reinterpretation of traditional cultural elements connect the past, present, and future. These forces also lead to the development of new creativity in the fashion industry. Three brands have been selected for case studies: Danha (Korea), Mittan (Japan), and Jan Jan Van Essche (Belgium). These brands possess in-depth understanding of traditional cultural elements, including clothing, dyeing techniques, and patterns unique to various regions and minority groups. The brands all make use of traditional cultural identities whose clothing contains the historical and sentimental values of various regions and ethnic groups. The use and mixing of various cultures can be seen as the respectful preservation of global culture. Also, in contemporary fashion, the use of traditional culture plays an important role in the presentation and development of creative designs. The use of traditional handicraft techniques and the use of traditional clothing in the past convey cultural diversity to future generations; they will have a lasting influence on future fashion trends. The results of the study show that cultural sustainability in contemporary fashion has been implemented through safeguarding and respecting indigenous cultures and developing cultural elements into creative design.

Indonesian women have emerged as global consumers, and various studies are needed to expand the global fashion market targeting their needs. In this study, a survey was conducted to determine the fashion design preferences of Indonesian Muslim women according to demographic characteristics and religious variables. In this study, Indonesian women aged from their teens to their 40s were surveyed by questionnaire during June 2020. This yielded 301 survey responses, which were analyzed using χ2-test, t-test, ANOVA, and Duncan's multiple range test using SPSS23. The results of the study are as follows: Analysis of the demographic characteristics of Indonesian Muslim women and the degree of acceptance of fashion trends according to religious variables showed significant differences according to age, monthly income, and the extent to which they wore a hijab. Analysis of the demographic characteristics of the women and the degree of acceptance of the fitted garment according to religious variables showed significant differences depending on their age, whether they were married, their monthly income, religious faithfulness, the extent to which they wore a hijab, and the degree of acceptance of Islamic discipline. After examining the difference in Muslim women’s preferred fashion images (according to demographic characteristics and religious variables), significant differences were identified according to their age, income, extent to which they wore a hijab, and the degree of Islamic discipline with regard to clothing.
