Sizing is the most common question our customers ask about when gifting. So we've made it easy.

All Organic Zoo clothes are designed for comfort and a relaxed fit. With lots of boxy and roomy styles suitable for all body shapes, our clothes are less size-sensitive.

Here are our tips for shopping our sizes:

For a newborn - 0-3m will be a perfect fit for most babies for the first 3 months. You can choose a size up if you want more room to grow into.

For toddlers - we recommend sizing up with tops for a more relaxed look. For bottoms & onesies, choose the appropriate age size. If in doubt, always size up.
