Size Guide
We follow Australian Standards for children's sizing which is bigger than European sizing but not quite as big as USA sizing. We've created a handy size guide table for selecting your size. Remember safety first when choosing sleepwear products and select the child’s true size. While growing room in every other style is always an advantage, it is especially important that sleepwear is worn snug thereby reducing the possibility of catching fire.
A child’s height is the best way to choose a size, because all kids grow at their own pace. Measure the child’s height from the top of the head to the floor. You should also consider their weight if a child is above or below average. If you are buying a gift, and do not have the child’s measurements, refer to the age guide and if in doubt order the next size up so they can grow into it or our gift card might be a great option.

Underwear size guide
Our entire collection runs true to Australian standards. Your best guide for underwear sizing is the clothes size you are buying for the upcoming season. That is the size we recommend you select in underwear with the exception of our unisex underwear collection. The unisex range is based on Australian standards for boys, so if you are purchasing the unisex style for a girl we recommend you size up.
More information regarding sizing is included in our product listings, including specific advice on which body shapes they are most suited to.
