Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.

US dress sizes run smaller than Australian ones by a consistent four points on the standard chart — a US 8 is an AU 12 — a bigger numerical jump than the US-to-UK dress conversion most American shoppers already know.

That larger gap is the detail that catches US shoppers ordering from Australian retailers off guard the first time: expecting a UK-style four-point-lower AU number can lead to sizing down when the chart actually calls for sizing up by that same margin.

Frequently asked questions

Is the US-to-AU dress gap the same as US-to-UK?

Yes, on the standard chart the Australian and UK dress numbering align (both four points above the US number), so if you already know your UK dress size, your AU size is usually the same number.
