Measuring an Ankara off-shoulder dress for kids is important to ensure the perfect fit. Here are the steps to measure a child for an Ankara off-shoulder dress:

1. Chest: Measure around the fullest part of the chest, under the arms, and across the shoulder blades.
2. Waist: Measure around the natural waistline, which is the narrowest part of the torso.
3. Hips: Measure around the fullest part of the hips, keeping the tape parallel to the floor.
4. Length: Measure from the top of the shoulder down to the desired hemline. For an off-shoulder dress, you may want to measure from the top of the shoulder to where you want the neckline to fall.
5. Arm length: Measure from the top of the shoulder down to the wrist.
6. Shoulder width: Measure across the back from one shoulder seam to the other.

Make sure to use a flexible measuring tape and ensure that the child is standing straight and relaxed while taking the measurements. It may also be helpful to have someone assist you to ensure accurate measurements. Once you have all the measurements, you can choose the appropriate size for the Ankara off-shoulder dress for your child.
