Abstract : This study aims to analyze the effect of product quality and fashion lifestyle on purchase decisions of thrift products in Rantauprapat and to examine the moderating role of digital marketing. A quantitative approach with a survey method was applied to 100 respondents. Data were collected using a Likert-scale questionnaire and analyzed using Partial Least Square-Structural Equation Modeling (PLS-SEM) with SmartPLS. The results show that product quality and fashion lifestyle have a positive and significant effect on purchase decisions. Digital marketing has a positive but not significant direct effect. As a moderating variable, digital marketing does not significantly moderate the relationship between product quality and purchase decisions, but it significantly strengthens the relationship between fashion lifestyle and purchase decisions. In conclusion, product quality and fashion lifestyle are the main determinants of purchase decisions, while digital marketing plays a limited strengthening role, particularly in relation to fashion lifestyle.
