The band should feel secure without digging in; cups and straps should feel comfortable as you move.

How the Chantelle guide works
Looks up your underbust and bust measurements in the manufacturer’s published body-chart cells. Missing cells, gaps and overlapping matches are preserved rather than replaced with a guessed size.

Bands are garment labels, not body ranges. Some combinations may be missing from this chart, and chart coverage is not a stock check.
Source scope and chart notes
Uses the manufacturer’s centimetre body table and its native French labels (80–135, A–J). French band numbers are size labels, not your measured underbust. Inches are converted to cm without rounding or extrapolating beyond printed ranges.
| Underbust | Bust | Label |
|---|---|---|
| 63–67 cm | 76–78 cm | 80A |
| 83–87 cm | 96–98 cm | 100A |
| 103–107 cm | 116–118 cm | 120A |
| 118–122 cm | 158–160 cm | 135J |
These are a few sample rows. Ranges can overlap in the official chart, and the calculator keeps those overlaps.
Let’s find your starting point
Measure over a t-shirt or a lightly lined bra, or without one—whichever feels right.
A number can guide you. Your comfort gets the final say.
Bra sizing isn’t consistent from one label—or even one style—to the next. Think of this as a useful first try, not a rule you have to fit.
If your first try is close but not quite right, compare neighboring sizes and another style or cut.
Brands use different patterns, fabrics, and size ranges. A mismatch says more about the garment than about you.
