Choosing the Right Size
Available age labels are 0–1 month and 1–3 months. These are approximate age ranges, not guaranteed measurements. The imported size chart contains inconsistent units, so exact garment measurements should be confirmed with the seller before ordering. Always check the selected variation and allow room for your baby’s comfort.
Care and Safety
Follow the garment’s care label for washing and drying. For supervised photography and awake wear only: remove the hat and any loose or decorative accessories before sleep. Keep pom-poms and other embellishments away from the baby’s mouth, inspect for loose parts before each use, and never leave a baby unattended while wearing the outfit. This outfit is not a substitute for safe sleepwear.
