Brooks to Berlei bra size

The short answer

Brooks L is Berlei 14C by the two brands' own charts.

Cups are counted along each brand's own letter order, and the band is carried across unchanged.

Every Brooks size read across to Berlei. Letter sizes on the left, AU on the right.

M	12C	not published	not published
L	14C	not published	not published

Neither chart publishes the body each size is built for, so the rows line up the labels. Tinted rows change label or sit between two sizes. Read from the two charts only; no formula and no averaging.
