In the competitive world of textile and clothing trade, there is a tendency to establish international strategic alliances between companies, seeking - among other benefits - additional resources, risk reduction, and production cost savings. For Brazilian fashion companies who want to internationalize their brands, the establishment of international partnerships can bring significant competitive advantages. The research at issue in this thesis aims to analyze the internationalization strategy of a Brazilian fashion retailer, and the implications of forming and maintaining its international alliances. Precisely, it seeks to analyze a Brazilian fashion retailer`s strategic fit (strategic choices and projections for the future) considering the international context in which the company operates. It is based on the assumption that it is important to consider the implications of alliances and networks, as well as that of the internationalization process for the company`s conduct and performance. The company focused upon is Osklen, a leader in the segment in which it operates. With a view to collecting the necessary data, in-depth interviews were conducted with executives of the company, who besides answering a questionnaire, provided information on the company`s international operations. In addition, public information available on websites specialized in the sector (also including the website of the company) was collected. The Strategic Network Analysis (SNA) tool, developed by Macedo- Soares (2002), was adopted for analyzing the data from a relational perspective. The SNA tool includes a methodology, a graphic model, in the sense of a map of the firm`s ego-net within its value net, and reference lists with relational constructs. The case study of this company added to these established reference lists new constructs that are particularly relevant to the fashion sector. Based on the results of relational analysis, the research strongly suggested that the establishment of strategic alliances has positive implications for the competitiveness of the company - providing enhancements of both company strengths and external opportunities, as well as minimization of company weaknesses and macroenvironmental threats. Finally, it was observed that Osklen’s strategic alliances have had-and continue to have-positive implications for the company’s internationalization process.
