How to measure and fit a bra in three easy steps
Warning! After a 38 band size, the band size should be the closest higher even number to your actual measurement. So 41.5″ is a 42 band. A 41″ measurement is a 42 band.
STEP 1: Measure for band size:
STEP 2: Measure for cup size:
STEP 3: *Calculate your bra size:
Subtract your band measurement (step 1) from your cup measurement (step 2). Generally, for each inch in difference, the cup goes up by one size. See the cup size conversion chart below.
Step 1: 34″ under measurement = 36″ band size
Step 2: 39″ over measurement
Step 3: 39″ – 36″ = 3″ or C Cup Size
Your Size is probably a 36C
The cup size calculation starts falling apart at 4 inches larger than your band size, and if you have droopy or pendulous breasts, your measurement will not be accurate.
