This page goes one level deeper than the brand profiles: instead of describing each brand's sizing in general terms, it lists the individual size rows we've recorded, in the manufacturer's own numbers. We keep each brand's ranges separate rather than assuming any two brands' labels mean the same thing.

Yellowberry uses multiple product-family charts. This seven-label family should not be substituted for its grouped seamless chart.
BRABAR is normalized as a method, not an alpha chart
BRABAR's published method rounds ribcage measurement to the nearest even band and maps bust-minus-band difference to cup size. For example, a one-inch difference maps to A, two inches to B and three inches to C. The database stores that formula separately instead of manufacturing a fake XS–XL translation.
Where this data comes from
We keep the source status, sizing family, verification date, measurement ranges, and notes on style exceptions all together internally, so nothing here gets stated with more confidence than the source actually supports.
