Measurements are approximate. Compare them with a similar garment that fits well; if between sizes, choose the larger size.

Our sizing is based on standard baby and toddler age ranges, but every little one grows at their own pace. For the best fit, we recommend choosing size based mainly on your child's height rather than age. If your child is between sizes, or if you prefer a more relaxed fit, we recommend sizing up.
