The study looked at how advertising influences consumer buying behaviour for clothing products in Chennai, India. Primary data was collected through questionnaires and secondary data was collected from documents. The study found that advertising plays a significant role in attracting attention, creating interest, and desire to purchase clothing items. The clothing industry uses various forms of advertising such as events, word of mouth, magazines, Facebook, trade fairs, T-shirts, and websites to provide information about cloth details, brand names, and price. The study recommends that companies should create advertisements in regional languages, reflect the local situation, provide direct information about the clothes, and offer more information about the benefits of the fabrics used in the clothing products.
