How Peach John sizing reads
Peach John reads on JIS-style centimeter bands identical to EU numbering, but the drawer's JP row matters: Japanese letters run one position deeper than Western ones, so a JP C cup equals a Western B. When Peach John lists an imported DD, that's a Western ladder spliced into a JIS catalogue: convert each notation separately rather than assuming one alphabet.
