FAQ
Should kids clothing size be based on age or height?
Height and weight are usually more reliable than age. Age is helpful for a quick starting point only.
What is the difference between 4T and size 4?
4T is usually cut for toddlers with more room for diapers and toddler proportions. Size 4 is often a little slimmer or longer.
Should I size up in kids clothing?
If the child is between sizes or growing quickly, sizing up is usually practical unless the item requires a close fit.
