Bundle to Bundle Sizing Guide
Your complete guide to finding the perfect fit across all our premium brands
Pro Tip: Children grow at different rates! While age guidelines are helpful, we always recommend measuring your child's height and chest for the most accurate fit. European brands especially size by height rather than age.

How to Measure Your Child
Height
Have your child stand barefoot against a wall with heels together. Mark the top of their head with a pencil or tape, then measure from the floor to the mark. This is the MOST IMPORTANT measurement for European brands!
Chest
Wrap a measuring tape around the fullest part of the chest (usually at armpit level), keeping the tape level and snug but not tight. The child should have their arms relaxed at their sides.
Waist
Measure around the natural waistline - this is where the body bends when your child leans to the side. Keep the tape comfortably loose.
