The 1920s in Bangkok marked a significant shift in Thai fashion, where the upper classes increasingly embraced Western styles, particularly the flapper look characterised by loose, knee-length dresses. During King Vajiravudh’s reign (1910–1925), traditional garments like the chongkraben were still worn, but women began to adopt the pha-sin, a tubular skirt, in conjunction with Western-style tops, reflecting a blend of influences. This period saw the pha-sin transition from a garment associated with rural women from other regions to one embraced by the Thai elite, largely due to its adoption by figures like Phra Worakanya Pathana. An article from January 5, 1920, urged women to wear the pha-sin instead of Western skirts, emphasising the importance of Thai identity amid growing Western influence. Thus, the 1920s represented a unique fusion of modern and traditional Thai fashion.
