NEW Size Guide – Double sizes (cm)
Choose by your child's height first, then chest measurement. Age is a guide only. These are body measurements, not garment measurements. Measure the chest around its fullest part.
| Size | Age guide | Child height | Chest |
|---|---|---|---|
| 3M (62) | 2–4 months | 62–68 cm | 40–42 cm |
| 6M (68) | 4–8 months | 68–74 cm | 42–44 cm |
| 9M (74) | 6–9 months | 74–80 cm | 44–46 cm |
| 12M (80) | 12–18 months | 80–86 cm | 46–48 cm |
| 1–2Y (86/92) | 1–2 years | 86–92 cm | 50–54 cm |
| 3–4Y (98/104) | 3–4 years | 98–104 cm | 54–58 cm |

| 9–10Y (134/140) | 9–10 years | 134–140 cm | 68–72 cm |
If your child is between sizes, we usually recommend choosing the larger size.
