Proper Measurement Technique
A
The Snug Ribcage (Band)
Keep tape completely parallel to floor. If you measure an odd number (e.g. 33"), round up to the nearest even number (34") for comfortable day-long wear.
B
The Fullest Apex (Cup)
Do not pull the tape tight. Let it skim across the nipples. The mathematical difference between Apex and Band determines your accurate Cup Letter.

3 Simple Steps to Your Flawless Foundation
No tailor needed. Use standard household sewing tape or any string matched against a ruler.
Step 01
Stand Relaxed & Straight
Stand in front of a mirror with arms relaxed. Exhale gently so your ribcage is at its natural resting volume.
Step 02
Check the Level in Back
Look in mirror from the side. Ensure tape does not sag or ride up between your shoulder blades in back.
Step 03
Calculate Cup Delta
Subtract underband from bust. Each 1-inch increase equals one cup jump: 1" = A, 2" = B, 3" = C, 4" = D.

The Golden Sister Size Rule
If the bra cup volume fits perfectly, but the band feels too tight or loose, adjust using inverse sister sizing:
Band feels too snug?
Go UP 1 Band, DOWN 1 Cup (e.g. 34B → 36A)
Band rides up your back?
Go DOWN 1 Band, UP 1 Cup (e.g. 34B → 32C)

Common Fit Issues Resolved
check
Spillage / Double Bust: Your cup is at least 1 size too small. Try size 34C instead of 34B.
check
Gapping / Loose Cup: Your cup is too large or the mold profile doesn't match your breast density. Opt for a plunge contour cut.
check
Straps Digging Into Shoulders: 80% of support should come from the underband, not straps. You likely need a smaller, firmer band.
