How to determine children's clothing size, you can follow these steps:

1. Measure Height: 📏 Have the child stand straight against a wall if possible. Measure from the top of their head to the floor.
2. Measure Chest: 👕 Use a measuring tape to measure around the fullest part of the chest.
3. Measure Waist: 👖 Measure around the narrowest part of the waist, usually just above the belly button.
4. Measure Hips: 🍑 Measure around the widest part of the hips.
5. Consider Growth: 📈 If the child is between sizes or growing quickly, consider sizing up for longer wear.
