How to Convert Bra Sizes

Converting bra sizes between countries is complex as cup sizes may differ while band sizes convert more straightforwardly.

US and UK band sizes are the same, while EU/FR band sizes are US + 18. For example, US 34C = UK 34C = EU 75C. Cup progressions can vary between systems, so always check brand-specific charts.

Proper bra fitting is crucial for comfort and support. Consider professional fitting when possible.
