How does the sizing work?

The product description states that this style is true to size and lists sizes from 0–3 months through to 18–24 months.

Please note that some of our clothing follows European/Spanish sizing. You may notice that the label shows sizes like 3 months instead of 0–3 months, or 6 months instead of 3–6 months — this is completely normal and reflects the European size standard.

We consider our clothing true to size, so we recommend choosing your little one’s usual size.
