How to Measure Your Bra Size
- Measure your underbust: Wrap a soft measuring tape snugly under your bust, directly below your breasts.
- Measure your overbust: Wrap the tape around the fullest part of your bust, keeping it level.
- Enter measurements above and select your unit and region.
Tip: For accuracy, measure without a bra or with a non-padded bra, standing straight.

Tips for Accurate Measurements
- Use a soft, flexible measuring tape.
- Measure while standing upright with arms relaxed.
- Ensure the tape is snug but not tight for underbust, and loose enough to avoid compression for overbust.
- Take measurements twice to confirm accuracy.
Common Bra Fit Issues
- Band too tight? Try a larger band size or sister size.
- Cup spillage? Go up a cup size.
- Straps slipping? Adjust straps or try a different bra style like a racerback.
- Underwire poking? Check band size or try a wireless bra.
