The present Doctoral Thesis elaborates a study on the social representations of androgyny in fashion ads published in VOGUE Brazil magazine between 1975 and 2018, with the objective of investigating the disciplinary capacity of the advertising discourse in presenting and representing the fluidity of contemporary identities, in this case, androgyny - the combination of feminine and masculine characteristics in one individual - and how it has been treated by the media culture. The research carried out is of a qualitative nature, with content analysis, through documentary research. The study proposes an interpretative historical analysis on the social construction of androgyny through the advertising stereotypes shown in the media. The construction of stereotypes, signs and meanings were analyzed under this perspective, relating them to the historical, political and sociocultural contextualization of each decade. The media are faced with contemporary men and women, social actors who are experiencing a time of transition in relation to previous models and who, consequently, question gender roles and identities which were constructed and standardized based on male/female binarism. With the present wealth of possibilities and a mistrust of certainties, we question the media: How does perception traverse social precepts based on cultural norms for the social representation of androgyny in Brazilian advertising? How much room is there for non-binary identities in a Western society anchored in gender binarism? How are advertising stereotypes built for ambiguous identity? The trajectory of some western societies, as is the case in Brazil, has, since the beginning of its constitution, been under male domination, transforming gender relationships, be they social or emotional, through methods of submission and power. Our main institutions, outside the home, have been conceived and operated primarily by men, functioning according to certain principles, attitudes and behaviors that are usually considered as masculine and, at home, principles, attitudes and behaviors that are usually considered as feminine. The understanding of gender relations implies that they are understood as the social constructions of identity, based on the biological differentiation of the sexes and expressed through relations of subordination and power, which define the activities, norms, and behaviors expected of men and of women. The starting point for this research is based mainly on Stuart Hall s studies of postmodernity and on Pierre Bourdieu s Distinction and Masculine Domination. It has been observed over the last four decades that changes in identities have been significant, shifting from identities to identifications. In the first decade, between the years 1975 and 1988, androgyny was anchored in unisex fashion. From 1989 to 1998, during the second decade, it was represented as illustrious, fanciful, luxurious, based on conspicuous consumption. During the third decade, comprised between 1999 and 2008, its representation took place through the jovialization of the models, of angelic stereotypes. In the fourth and final decade, between the years 2009 and 2018, the social representation of androgyny has become fluid. Such transformations have made room for new non-binary social representations.
