How to Measure Your Child
1. Height
Measure barefoot from the top of the head flat down to the floor while standing against a wall.
2. Chest
Place the tape measure under the arms and across the fullest part of the child's chest horizontally.
3. Waist
Measure around the natural waistline, keeping the tape comfortably loose to allow room for movement.
4. Hips
Measure around the fullest part of the hips and bottom with heels together.
💡 Pro Sizing Tip: Children grow fast! If your child’s measurement falls between two sizes, we recommend selecting the larger size for longer wear and better comfort.
