The paper explores the emergence of class boundaries in postsocialism in the realm of sociability. The goal was to observe class dynamics through qualitative, experience-near approach, providing a dynamic account of the ways Croatian upper middle class draw symbolic boundaries toward people of different social status. Two main patterns of symbolic boundary maintenance are described and observed in their historical trajectories. The issue of symbolic boundaries is then explored in case of private schooling, in order to follow the process of institutionalization of class inequalities. Finally, an opposite trend of boundary transgression is demonstrated on the case of cross-class friendships
