Changes in demographics and availability of global clothing brands have brought several changes in Indian apparel industry. Green or organic clothing brands are becoming popular among Indians and likely to contribute to the revenues of apparel sector. Global and national apparel manufacturers have introduced organic clothing lines to cater to ecological conscious consumers. The purpose of this research was to examine the effect of consumer susceptibility to interpersonal influence (CSII), past green behaviour, green peer influence and green apparel knowledge on Indian youth's green apparel buying behaviour. A mix of convenience and random sampling was used for data collection. The sample (n = 981) comprised of youth of age group 18–24 years. Structural equation modelling was used to test the hypothesized relationships. Findings suggest that past green behaviour influenced green apparel buying behaviour. Green peer influence and green apparel knowledge had no impact on green apparel buying behaviour. Moreover, CSII had no influence on green apparel buying behaviour. The findings differ from earlier studies that suggest influence of social norms and peer group had an effect on green buying behaviour. Practical implications of the present study are discussed.
