Frequently Asked Questions
How often should I measure myself?
We recommend measuring every 6 months or after weight changes (±3kg), pregnancy or breastfeeding. Breast tissue changes with hormones, age and weight fluctuations.
Why do sizes vary between brands?
Each brand uses their own sizing charts and different cutting systems. For example, Victoria's Secret tends to run smaller than Wacoal. Our calculator adjusts for these variations.
How do I know if my bra fits well?
Signs of good fit:
- The band stays parallel to the floor (doesn't ride up your back)
- The underwire doesn't press into breast tissue
- The cups have no gaps or spillage
- You can slide two fingers under the shoulder straps
