Frequently Asked Questions

How do I know when to size up for kids' pants?

Size up when pants are tight at the waist or too short in length. Children grow quickly, so choosing a slightly larger size often provides better value and comfort.

What do EU kids' pants sizes mean?

EU kids' sizes are based on the child's height in centimeters. For example, size 128 is designed for children approximately 128cm tall, typically ages 7-8 years.

How do I measure my child's waist for pants?

Measure around your child's natural waistline (above the hip bones). Have them stand straight and breathe normally. For adjustable waist pants, measure at the tightest comfortable setting.
