Fitting Tips

🎗️
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.
