FAQ: Bra Size Conversion

Not always. Most brands follow standard conversions, but sizing can vary by style, fabric, or manufacturer. Always try bras on when possible and check the brand’s own sizing chart for final fit[2][5].
If your exact band or cup isn't available in another region, try the nearest sister size or adjust up/down within comfort. Our charts match the closest standard sizes used worldwide.
Cup letters may shift across systems (e.g., UK DD ≈ US DD/E ≈ EU E), but usually the charts map cup volumes as closely as possible by difference between band & bust. Always check the conversion result to ensure fit.
Yes! Most Indian brands use UK sizing. Use the UK option for accurate conversions, and consult the EU or US tab if shopping for imported styles.
