Bra Sizing Tips & Information
Proper Measuring
Measure your underbust snugly and round to the nearest even number for band size. Then measure bust at fullest point and subtract band measurement to determine cup size.
Sister Sizes
Sister sizes have the same cup volume. If 34C feels tight in the band, try 36B. If the cup is too small, try 34D or 32DD.
International Differences
EU uses centimeters for band size. UK and US diverge at DD cup (UK uses E instead of DDD). Japanese sizes are often smaller than Western equivalents.
Fit Check
The band should be snug and parallel to the ground. Cups should fully contain breast tissue without gaping or spillage. Center gore should lie flat against sternum.
