TAPE FIT1 FingerUnder the cupsCUP VOLUMENo PressAcross apex

Tape snug right under your bust, level all the way round. Breathe out first.

Enter both measurements to see your size.

Tips for measuring
Side view. Correct: the tape is level, straight across the back. Wrong: the tape droops at the spine
Keep the tape level. If it droops at the back, the size comes out too big.
Three tape tensions seen from above: too tight digs in, just right lies flat, too loose gaps and slips
Snug, not tight. The tape should lie flat against your body without pressing in.
A measuring tape: inches along the top edge, centimetres along the bottom edge, both starting at 0
Inches or cm. One edge of the tape shows inches, the other shows cm. Read the number where the tape meets its 0 end.
No tape: wrap a string round, then lay it flat along a ruler and read the length between the marks
No tape? Wrap a string or shoelace round, pinch where it meets, then lay it flat along a ruler and type that length in.

Cup volume scales with the band. That means a 34B holds the exact same cup volume as a 32C (snugger band) and a 36A (more relaxed band).

  • Band feels too tight? Go up one band (+2) and down one cup letter (e.g. 34B to 36A).
  • Band rides up at the back? Go down one band (-2) and up one cup letter (e.g. 34B to 32C).
  • Start on the loosest hook: A new bra should feel comfortably snug on the outermost hook so you can move to tighter hooks as the fabric relaxes over time.
