Find the perfect fit for your little adventurer
We know one of the biggest challenges for parents shopping online is knowing which size to choose — especially when every child grows differently and sizing can vary between brands. At Kidz Under Construction, we want to make choosing the right size simple, stress-free and as accurate as possible.

Our sizing philosophy
We’re committed to making sizing as easy and straightforward as possible for parents. Because every child is different and sizing can vary between styles, we recommend checking the individual size chart and measurements provided with each product rather than relying on age alone.
Tips for measuring
Our biggest tip? Measure your little adventurer before ordering. It only takes a minute and can make choosing the right size so much easier. We’ll also include helpful information about how each style fits — whether it’s a relaxed, regular or oversized fit.
What makes our clothes unique?
We want Kidz Under Construction clothing to be comfortable, practical and ready for adventure. Depending on the style, some pieces may feature comfortable, flexible fabrics and relaxed fits designed to give little legends plenty of freedom to move, play and explore. We’re also focused on creating practical everyday pieces that kids can actually enjoy wearing — whether they’re climbing, digging, running around or simply hanging out with their mates.
