In order to create their social identity, humans have a tendency to express their feelings and self in the form of views and opinions that they expect from their immediate society. In today’s tech-savvy world, social media has become the most important platform for expressing one’s feelings, experiences and creating self-identity. Subcultures based on these online identities have a direct or indirect effect on fashion, subculture, intercommunity (individuals within the subculture community) and intracommunity (individuals outside the subculture community) individuals. The rise in popularity of social media platforms has led to the recreation of such subculture communities as an online trend. The current article talks about the relation between fashion, social media and these online identities. Multiple identities that are shaped and expressed through fashion and style are created and enacted through social media. Multiple case studies were analysed for qualitative secondary research to understand the effects of recreation of multiple online subcultures, which was filtered down to the Cottagecore, E-girls and Dark Academia subcultures while keeping in mind the relevance on social media and availability of resources. These were taken as interviews from articles and blogs as secondary research pertaining to each subculture. The objective of the article is to understand the effects of recreation of online subcultures on the particular subcultures, its intercommunity, intracommunity individuals, as well as the fashion industry. Mixing and recreation of subcultures create different styles and aesthetics; thus, fashion keeps changing according to that, and trends keep coming up in the fashion industry.
