This study aims at describing controversial messages in advertising, and analysing the consumers‟ attitudes towards it. For this research, both primary and secondary sources were used, as we collected data from three focus groups, as well as information from the media concerning the advertising campaigns used. Said campaigns are: United Colors of Benetton “UNHATE”, Sisley “Fashion Junkies”, and a sample of some American Apparel advertisements. Through this research, we elaborated the relationship between the messages carried by controversial advertisements and the decisions taken by consumers. Our findings show that the outcomes and impact of controversial advertisements are hardly predictable, but they are influenced by the content of the message and the way it is presented. We also present a link between the consumers‟ decision-making process and their attitudes, together with how controversial advertisements impact those attitudes and reactions towards a brand or its products.
