Can my bra size change over time?

Bra sizes change throughout life as a natural response to various biological processes and life events. Your breast tissue responds to hormonal shifts during menstrual cycles, pregnancy, and menopause, while natural aging and weight fluctuations also influence their shape and volume.

As your body's relationship with estrogen evolves, breast tissue density and elasticity change, often necessitating different bra sizes during different life stages. Many women experience these changes without realizing they need new measurements, which explains why it's recommended women measure their bra size every six to twelve months.
