Tips for the perfect fit
Measure recently
Kids grow fast. If your measurements are more than a month or two old, take fresh ones before picking a size.
When in between sizes
Choose the larger size. It's easier to take a garment in slightly than to outgrow it after a few washes.
Different sizes for top & bottom
If chest and hips fall into different sizes, choose the larger one and adjust the other area when assembling the pattern.
Measure over light clothing
Thin t-shirt and leggings are fine. Avoid bulky sweaters or thick layers — they add a few centimeters to every measurement.
