🦶 Tip: Trace your baby's foot on paper and measure the outline for the most accurate fit.

  • 👶 Size up when in doubt — babies grow fast and boutique cuts can run snug.
  • 👗 Dresses & rompers — fit is driven by height and chest; check both columns.
  • 🧥 Layering seasons — size up one for room to layer in fall/winter.
  • 👟 2T vs. 24M — 2T is slimmer and longer (toddler cut); 24M has a roomier diaper allowance.
  • 📦 Gifting? — always size up; a 6M gift for a newborn gives more wear time.
  • 🌿 Organic & wool fabrics — may have less stretch; when between sizes, go up.
