The complete dress size chart

There is no law — anywhere — that defines a dress size. Standards bodies publish reference body measurements (ASTM D5585 in the US, the ISO 8559 series internationally), but no brand is obliged to cut to them, and most publish charts that drift from the standards and from each other.

So this chart was built the only defensible way: published size charts from major retailers and standards references were cross-checked line by line, and where they disagreed, the consensus value was taken. The disagreement is real and worth knowing about: across published charts, a US 10 bust appears anywhere from 36.5″ to 39.5″. This chart prints 38″ — the top of the most common published range — because a chart used for ordering decisions should err toward the garment closing.

The grading pattern that emerges is consistent: sizes step about 1–1.5″ apart through the middle of the chart and 2″ apart at the ends; UK labels run exactly 4 above US labels, EU labels 32 above, and Australian labels share the UK numbers. Those three conversion rules hold across every row — which is why the converter can be simple arithmetic while the measurements behind it cannot.

The practical consequence, printed here rather than buried: use this chart to find your size, then compare your measurements with the specific brand's chart before ordering. Where the two disagree by more than an inch, believe the brand about its own clothes — and believe this chart about your body.
