Sizing up depends on how your child fits within the current size range.
We recommend sizing up if:
• Your child is near the top of the weight or height range
• You prefer a slightly roomier fit
• You want to maximize how long the item will last
Thanks to the stretch in our bamboo fabric, sizing up typically still fits comfortably—just with a little extra room to grow.
If you’re unsure, sizing up is the most common choice.
