Using Pop
Two inserts do not need to be judged by whether they sit at identical ruler measurements. What matters is that each stays within its bra cup and feels comfortable. Use the outfit's neckline and your natural shape as the final fitting reference.
Explore Pop insertsAdjust one cup at a time
Start with one insert inside each cup. Make small changes and compare the result under your top. Avoid chasing exact symmetry by overfilling one side or moving an insert outside the cup's covered area.
Check after normal movement
Sit down and reach forward, then return to the mirror. Check whether the bra and inserts still sit comfortably. If you need repeated adjustments to keep the neckline covered, try a different bra or outfit fit.
Your fitting checklist
- Keep both inserts covered
- Adjust in small steps
- Recheck after sitting
Use the VELUNA size guide for the relevant product. Follow the instructions supplied with your product.
A common question
Should both inserts sit in precisely the same position?
Follow your product instructions and choose comfortable placement within each cup rather than relying on identical measurements.
