The current study is aimed to gain insights into buying behavior and other aspects pertinent to online purchases and related experiences regarding fashion products in the city of Mumbai Metropolitan, the largest fashion hub in India. A cross-sectional survey design was employed to collect data from consumers with diverse parameters. The survey questionnaire based on a comprehensive literature review and consultation with experts was created as a Google form and was circulated via online platforms, including social media groups and email lists. The data reveals that younger age groups, particularly those aged 18-30 and under 18, are the most active participants in online shopping for fashion products, with significant representation across all shopping percentage categories. The prevalence of respondents in the 10-30% and 40-60% shopping categories suggests a varied level of adoption of online fashion shopping, indicating potential for growth with targeted marketing efforts. Understanding these demographics' preferences and motivations can inform strategies to enhance online shopping experiences and further increase participation among diverse consumer segments. The study highlights that the convenience, variety, and price were the main factors influencing buying decision for fashion products online. The social media and recommendations from friends/family were also of paramount importance as sources of information for making purchasing decisions. Furthermore, it was observed that customers had positive experiences with their previous online purchases. However, the factors like delayed delivery and sizing issues still remain major de-motivating factors for online buyers. Despite such challenges there is a positive attitude towards online shopping of fashion products. This study provides valuable insights into the buying behaviour of consumers in Mumbai Metropolitan regarding online fashion purchases. These findings can help businesses understand consumer preferences better and tailor their strategies accordingly to improve customer satisfaction and loyalty in this highly competitive market.
