On Running Women's Clothing Size Guide
On women's clothing uses standard XS–XXL sizing. The AU column below is the equivalent Australian dress size — an On M is roughly an AU 12. On cuts its apparel true to size, so order the size you normally wear.
| Size | AU size | Bust (cm) | Waist (cm) | Hip (cm) |
|---|---|---|---|---|
| XS | 8 | up to 82 | up to 67 | up to 90 |
| S | 10 | 83–88 | 68–73 | 91–96 |
| M | 12 | 89–94 | 74–79 | 97–102 |
| L | 14 | 95–100 | 80–85 | 103–108 |
| XL | 16–18 | 101–109 | 86–95 | 109–115 |
| XXL | 20 | 110–118 | 96–105 | 116–122 |
On labels each garment with its own fit — Close, Regular or Relaxed. A Close fit is deliberately body-hugging for racing and is not a sign to size up. AU dress sizes are indicative; go by the centimetre measurements where you can.
