Frequently Asked Questions

How do I measure my child's chest for shirts?

Wrap a tape measure around the fullest part of your child's chest, under the arms. Keep the tape snug but not tight, and ensure they're standing straight and breathing normally.

What do EU kids' sizes like 128 or 140 mean?

EU kids' sizes are based on height in centimeters. Size 128 is for children approximately 128cm tall (about 7-8 years old), while 140 fits children around 140cm tall (9-10 years old).

Should I size up for kids' clothing?

If between sizes, sizing up is usually best since children grow quickly. A slightly larger shirt can be worn longer and provides more comfortable movement.
