Sister sizes of 44B

A sister size moves the band one step and the cup one letter the other way.

For 44B, cup B corresponds to a bust of 45.5 to 46.5 in on band 44, with the upper endpoint excluded. The difference is rounded to whole inches, so the interval identifies the cup for this band.

The underbust method gives band 44 from an underbust range that does not overlap the add-4 method range for that band. Published charts disagree: the underbust method uses the underbust itself, while the add-4 method first rounds it and then uses the parity of the resulting number. The EU method gives the same body band 100, shown here as 100B, while US and UK retain 44B.

The sister size one step down is 42C, and one step up is 46A. For 44B, the JP tag reads 100C, one letter later than the EU cup B; JP letters vary by brand. The larger sister size shown two steps up is 48AA.
