Measuring guidelines

Height

Measure from the top of the head down to the ground - ensuring the child is barefoot and has his or her heels together and feet flat on the floor.

Chest

Take the tape through the arms and around the fullest part of the chest.

Waist

Place the tape measure around the natural waistline, taking care not to pull it too tightly.

Hips

Place the tape measure around the fullest part of the bottom.

Inside leg

Measure with shoes on, to approximately 5cm above the ground.

Collar

Place the tape measure around the base of the neck where the collar usually sits, again taking care not to pull the tape too tightly as it is important to have a little extra room around the neck.

Tips

  • If you can, buy 3-4 tops for every 1-2 bottoms within the
    same range, and you'll give yourself mix and match options
  • Buy co-ordinating hosiery at the same time
  • Wash garments at the coolest possible temperature;
    it helps keep them looking newer for longer
