A comparison of the TPB model and extended models showed that the TPB model itself, consisting of attitude towards purchase, subjective norm and perceived behavioural control as determinants of intention, has worse results compared to the extended model, therefore, in order to explain the intention to purchase eco-certified clothing, its expansion with other variables is appropriate. The extended TPB model showed that other factors are also determining the intention. By adding additional variables to the model, the perceived behavioural control lost statistical significance at the 95% significance level. With a greater interest in the origin of fashion and environmentally friendly behaviour, a growing subjective norm, with greater knowledge of certificates and with a better attitude towards the purchase of certified clothing, the intention to purchase such clothing is growing. The model extended by sociodemographic variables did not show a statistically significant..
