Quick answer
Choose your child's size based on their current measurements—especially height and chest—rather than age alone, and size up if they're between sizes or you want extra room for layering. For the AW24 A0BM1 long-sleeve tee, start with the size that matches their usual Petit Bateau fit.
Why age-based sizing can be misleading
Kids grow at different rates, so a size labeled for a certain age may not match your child's actual body. Always check the brand's specific size chart and compare it to your child's current measurements, not the age on the tag.
How to measure for a reliable fit
Use a soft tape measure to record height, chest, waist, and hip. Measure over lightweight clothing and keep the tape snug but not tight. If your child is between sizes, consider how you want the garment to fit—snug for layering or roomy for growth.
When to size up (and when not to)
Size up if your child is at the top of a size range, if you plan to layer the item over other clothes, or if you prefer a relaxed look. Avoid sizing up too much for fitted styles, as it can affect comfort and safety.
Kids' sizing questions answered
How do I choose the right size for my child?
Take your child's current height and chest measurements and compare them to the size chart for the specific brand. If they fall between sizes, decide based on desired fit: size up for room to grow or layering, or stay with the smaller size for a closer fit.
Should I size up for the AW24 A0BM1 long-sleeve tee?
The AW24 A0BM1 is designed as a long-sleeve tee for cooler days. If your child is between sizes or you plan to layer it over a light top, sizing up can provide extra comfort. Otherwise, choose their usual size for a standard fit.
What if my child is between sizes?
Check the brand's size chart and consider the garment style. For looser styles, the smaller size may work; for fitted styles or if you want growth room, go with the larger size. Remember that hem and sleeve lengths are often the first to feel short.
How can I tell if a size chart is accurate?
Look for charts that provide measurements in inches or centimeters, not just age ranges. Compare your child's measurements to the chart and read any fit notes. If possible, check reviews for feedback on whether the item runs true to size.
