Social media marketing has provided easy access to consumers. Luxury brands frequently keep posted their collections and proceedings on social media with the aim to save interest, engagement, create awareness as well as shape loyalties. This research is conducted in three randomly selected cities of Pakistan. The population of this research study involves all females aged 18 to 35 years and residing in Lahore, Karachi and Islamabad. A multistage random sampling technique was used; a representative sample of 350 women social media users was interviewed. Results show that the most relevant factors that seem to be affecting consumer buying behavior are social media marketing. The chi-square test showed that there is an association between social media usage and buying behavior. Regression analysis accepts the hypothesis that women buying behavior is dependent on social media marketing as well. So it is concluded that women buying behavior is influenced by social media marketing.
