Our paper analyses data from four Heads of elite fee-charging girls' schools in Scotland, focusing on how two social landscape changes -- changing pupil demographics and pressures on schools' charitable status -- may have reshaped the schools' institutional habitus. Following Bourdieu, we examine this question through the concept of habitus clivé. Shifting national-scale demographics and institutional pressures to fill expensive pupil places has generated a more diverse student population both in terms of academic ability and cultural background. Maintaining charitable status has, in turn, involved opening their space to non-school others, and developing interactions with the broader community. Insights are offered on how, despite these significant changes, schools' current habitus commitments continue to align with their founding principles, while also adapting to these new contextual realities, as they seek to ensure their girl pupil subjects can succeed in the 21st century.
