Size Guide
Pick the right fit for your little one — age bands, measurements, and fit notes.
Last updated: 14 February 2026
Our sizing is based on age, but every baby is different. Use the guide below as a starting point and size up if your little one is on the bigger side — muslin holds its shape well, so a slightly looser fit will still look right.
Age Bands
- Newborn (0–3 months): 50–62 cm, 3.5–6 kg
- Tiny One (3–6 months): 62–68 cm, 6–8 kg
- Little Explorer (6–12 months): 68–76 cm, 8–10 kg
- Toddler (1–2 years): 76–88 cm, 10–13 kg
Fit Notes
Co-ord sets and jablas have generous arm and leg room to make changes easy. Frocks are intentionally roomy at the bodice so you get a few extra months of wear.
