This study examines the historical roots of Islamic dress and its implications in a global context. Tracing the evolution of Islamic dress from its earliest requirements to modern times, the article examines its religious, social and cultural functions. It examines the limits and prohibitions imposed by Islamic law on the clothing of men and women, as well as the manners of veiling based on the Quran and Sunnah. The study highlights the role of historical trade routes and the development of global economic markets, which have led to the spread of Islamic clothing across different geographies and the enrichment of different cultures. Furthermore, the study analyzes the role of Muslim consumers as a key factor influencing the emergence and rapid growth of the modest fashion industry in the 21st century and forecasts that demand will increase at the macrotrend level. Combining historical analysis with economic and cultural perspectives, this article examines how Islamic dress functions today as both a symbol of identity and a significant economic force. Research can be an impetus for cultural development, the enrichment of religious clothing varieties not only as modest styles, but also as Islamic clothing according to Muslim Sharia laws and multidisciplinary discussions on global market dynamics.
