Step 1 — Band Size
Wrap the tape firmly around your ribcage, directly under your bust. Keep it snug and parallel to the floor.
Exhale normally while measuringStep 2 — Bust Size
Measure around the fullest part of your bust. Keep the tape loose — not tight.

Measured at the fullest point
If the band feels too tight, try the same cup in the next band up.

The Band Does the Work
90% of support comes from the band. Only two fingers should fit underneath.
Underwire Should Lie Flat
The underwire should rest against your ribcage without digging in.
Straps Carry Only 10%
If you tighten straps a lot, your band size may be too large.
Start on Loosest Hook
Always fasten a new bra on the loosest hook so you can tighten as it breaks in.
Sister Sizes
34B = 32C = 36A in cup volume. Up one band, down one cup gives the same fit.
Re-measure Every Year
Weight changes and age affect your size. Re-measure at least once a year.
