Our briefs are made from a beautifully soft modal fabric with a gentle stretch of up to 5 cm, so they fit closest to the measurements below.
✅ Step 1: Measure around your child's waist where they like their underwear to sit. A soft tape measure works best, or use a piece of string and measure it against a ruler.
✅ Step 2: Find their measurement in the Fits waist column below. Go by the measurement rather than age.
| Size | Fits waist | Approx. age |
|---|---|---|
| 4–6 | up to 51 cm | 4–6 |
| 7–9 | 52–56 cm | 7–9 |
| 10–12 | 57–61 cm | 10–12 |
| 12–14 | 62–66 cm | 12–14 |
