Record numbers in inches and centimeters to compare with charts. Measure twice on different days if hormonal fluctuation affects you.
Applying numbers
Sister size when bands feel wrong but cups are close. Re-measure after weight change or new training regimen.
Fit references
Compare against styles like the Rose Blush Underwire for structured sizing, the Blush Rose Two-Piece for stretch lace sets, and the Ivory Seamless Bra for molded simplicity.
Conclusion
Numbers are a map, not a verdict—use them alongside comfort tests and movement.
