A quantitative explanatory approach was used with 150 respondents chosen through purposive sampling, analyzed using Structural Equation Modeling (SEM) via AMOS. Results show that social media fashion influencer relatability has a positive and significant effect on purchase decision and perceived emotional value. Perceived emotional value positively and significantly affects purchase decision and partially mediates the effect of relatability.
