The paper attempts to trace and document an instance of the influential power of a regional TV serial in creating a form of popular local culture embedded in the Bengali community’s socio-cultural history and identity. 2017 onward, the sudden popularity gain of the typical characteristic 19th-century style of Bengali traditional men’s attire in Kolkata markets, simultaneously with the growing popularity of a TV serial “Korunamoyee Rani Rashmoni” (dir. Rupak Dey, 2017–22) prompted the researchers into making a descriptive claim. The storyline followed the life of social reformer Rani Rashmoni in colonial Bengal and showed primarily zamindars clad in traditional 19th-century attire. This TV series, “….Rashmoni,” is a rare example of visual media promoting its own cultural heritage in a community through design ideation and synthesis, simultaneously demolishing the class barriers associated with the visual design in question, achieving an outstanding act of social responsibility. By using visual ethnography and narrative analysis as methodology tools while interviewing men’s apparel sellers and independent designers from Kolkata, the study locates both visual and social media influence on Bengali men’s choice of clothing- ranging from following celebrities’ unique styles to desiring to adopt distinctive looks seen on TV, seeking appreciation from netizens and personal social circle. The research offers a visual analysis of the evolution of period drama costumes for male characters represented in Bengali media and their subsequent effect on general customers’ fashion choices. It sheds interesting light on the gender roles in purchasing decisions in relation to the viewership of fictional televised content. The paper concludes by indicating the resilience of the trend through the global pandemic, substantially outliving its source of inspiration even in 2024’s Kolkata, proving the potential of design ideation and synthesis of visual media in its regional cultural stronghold.
