The emergence of new economy has brought the creative industries onto the urban research agenda. Despite the extensive literature on the subject, there is need of a more in-depth approach to investigation the unique formations of creative industry clusters. The aim of this dissertation is to explore the particular organizational and spatial structures of creative industry clusters from the ecosystem perspective. This present study recognizes the fashion industry as a creative industry and the wedding wear sector as its subset. Then, it investigates how the cluster of wedding wear sector operates as an ecosystem in terms of the diversity, interaction, competition and evolution in the case of Mimar Kemalettin Fashion District. The methodology consists of the literature review, preliminary field studies, development of the DICE model which explores the diversity, interaction, competition and evolution of ecosystems in a particular space, pilot study for testing the model, data collection via site visits, DICE survey and additional interviews on site, data processing through descriptive analyses and regression analyses, and conclusions. The findings reveal that the existing cluster is young and emerging. This ecosystem currently self-operates with shortage of diversity in a concentrated spatial structure. The role of geographical proximity and the existing local buzz are substantial on excessive internal interactions. The existing competitive atmosphere is portrayed as a win-lose situation and there is a considerable disinterest towards to collaborations. For evolution, the ecosystem mutually co-evolve with mutation occurred inside the firms. Also, the crossover is found primarily a localized phenomenon.
