How to Measure Accurately at Home
1. Wear an unpadded bra
Thick push-up padding distorts true ribcage and cup contours.
2. Keep tape level
Ensure the tape measure stays parallel to the floor front to back.
3. Snug underbust
Exhale and measure firmly beneath the breast tissue crease.
4. Gentle overbust
Measure across the fullest projection without compressing breast tissue.
