The 36B label pairs band 36 with cup B in US and UK tags. For this label, a bust of 37.5 to 37.5 to 38.5 in falls in cup B under both the underbust method and the add-4 method.
For 36B, the add-4 method uses an underbust span that the EU method assigns to band 80. Published charts disagree about which band the same body receives: the underbust method and add-4 method give band 36 from non-overlapping underbust ranges. The EU method groups bands at 5 cm intervals.
The 36B sister size one step down is 34C, while one step up is 38A. JP marks this cup difference with C, giving 80C for the corresponding label; JP letters vary by brand.
