Quick Answer

Petit Bateau kids' shirts are designed with a European slim fit and soft, durable cotton that holds its shape. For the best fit, size up if your child is between sizes, and always check the fabric care label to keep the cotton feeling soft.

Understanding the Fit

Petit Bateau shirts typically have a slim, tailored fit that follows the European aesthetic. This means they are not as boxy as many US brands, so if your child is used to a looser fit, consider going up one size. The brand offers a range of sizes (e.g., 3A, 5A, 6A, 8A, 12A) that correspond roughly to age, but always measure your child's chest and compare to the size chart for the most accurate fit.

A common mistake is assuming the size label matches US sizing. For example, a size 8A in Petit Bateau fits a child with a chest measurement of about 22 inches, which is smaller than a typical US size 8. Always check the specific garment's measurements, especially for shirts and tops.

Fabric Quality and Care

Petit Bateau is known for its high-quality cotton, which is often pre-shrunk and has a soft, dense weave. This means the fabric feels smooth against the skin and holds its color well after washing. However, to maintain that softness and prevent pilling, always wash in cold water and tumble dry on low heat. Avoid fabric softeners, as they can coat the fibers and reduce breathability.

The brand's cotton is also durable enough to withstand frequent washes, which is essential for active kids. The lobster logo tee, for instance, uses a sturdy cotton that stays crisp even after many cycles.

How to Choose the Right Petit Bateau Shirt

  1. Measure Your Child's Chest: Use a soft measuring tape around the fullest part of the chest, just under the arms. Keep the tape snug but not tight. Write down the measurement in inches. Common mistake: Relying only on age. A 5-year-old with a 21-inch chest may need a size 6A instead of 5A.
  2. Compare to the Size Chart: Petit Bateau's size chart lists chest measurements for each size. Match your child's measurement to the nearest size. If they fall between two sizes, choose the larger one for a more comfortable fit. Checkpoint: The shirt should allow about an inch of ease for movement. If it's tight, size up.
  3. Consider the Style and Fabric: Short-sleeve tees like the lobster logo shirt are lightweight and perfect for warm weather. For a more fitted look, stick with your child's regular size. For a looser, more relaxed fit, size up. Verdict: A size up gives room to grow, but the shirt may look slightly oversized. Choose based on how you want it to fit.
