How sister sizing works

Sister sizes keep cup volume close while changing band tension. Down one band, up one cup. Up one band, down one cup.

Common mistakes

  • Changing the band but forgetting to adjust the cup in the opposite direction.
  • Comparing different bra styles at once, which makes fit feedback harder to trust.
  • Assuming cup letters are absolute volume across all band sizes.
