Size Chart

Finding the right size

To get an accurate body measurement, do not measure over clothing.

  • Chest: With your child's arms out, measure around the fullest part of the chest.
  • Waist: Measure around the natural waistline.
  • Hip: Measure around the fullest part of the hips and seat.
  • Height: Measure from the top of the head to the ground, without shoes.

When purchasing kid's pajamas, we recommend buying a size up from the age of the child (example: a four-year-old would take a size 5).

Adult Union Suits

As the adult union suits are unisex, sizing is based on a man’s average proportions (it has to fit him too!) To select the right size for a woman, choose one size smaller than normal. Ex: if she normally wears medium, select a small.
