Which measurements give a 28C
The label is a band and a cup, not a body measurement. Each of the three published rules turns the same label into different measurements.

|---|---|---|---|
| Underbust method | 27 to 29 in | 68.58 to 73.66 cm | 30.5 to 31.5 in |
| Add-4 method | 22.5 to 24.5 in | 57.15 to 62.23 cm | 30.5 to 31.5 in |
| EU method, band 60 | 22.64 to 24.61 in | 57.5 to 62.5 cm | Cup read in cm |
Each range includes its first figure and stops just short of its last.

Sister sizes of 28C
A sister size moves the band one step and the cup one letter the other way.
For 28C, a bust range of 30.5 to 31.5 in corresponds to cup C under both the underbust method and the add-4 method. The band is a tag label, while your bust measurement helps identify the difference.
The same 28C label appears as 60C in EU, 75C in FR/BE, and 6C in AU/NZ; US and UK retain 28C. JP uses 60D, so its letter differs from the C shown in EU. Published charts disagree about how measurements produce the band: the methods use different rules.
One sister size for 28C is 30B in US and UK, 65B in EU, 80B in FR/BE, 8B in AU/NZ, and 65C in JP. Two steps up, US and UK show 32A and EU shows 70A; the JP table does not list that step.
