Which measurements give a 42C
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.
| Method | Underbust (in) | Underbust (cm) | Bust (in) |
|---|---|---|---|
| Underbust method | 41 to 43 in | 104.14 to 109.22 cm | 44.5 to 45.5 in |
| Add-4 method | 36.5 to 38.5 in | 92.71 to 97.79 cm | 44.5 to 45.5 in |
| EU method, band 95 | 36.42 to 38.39 in | 92.5 to 97.5 cm | Cup read in cm |
Each range includes its first figure and stops just short of its last.

For 42C, a bust from 44.5 to 45.5 in leads to cup C under either method. The upper endpoint is excluded, and this is the bust range linked to the label.
Published charts disagree on which underbust corresponds to band 42. The underbust method uses 41 in up to but not including 43 in, while the add-4 method uses 36.5 to 38.5 in, with the upper endpoint excluded. The EU method assigns band 95 to 92.5 cm up to but not including 97.5 cm. These methods do not overlap for band 42, so no underbust maps to it by both.
The EU label for 42C is 95C, while its US and UK labels retain 42C. The same bust range leads to cup C under both methods, despite their different underbust ranges for band 42.
