What to Compare Before Buying

  • Size: The set is marked 2-3 years, so compare that with the child’s usual fit and the measurements you expect.
  • Format: It is a top and bottom set, so check that you want both pieces together.
  • Fabric: The set is described as cotton, so compare it with your preference for everyday nightwear or layering.
  • Use: It is positioned as spring and winter sleepwear, so decide whether you want it mainly for layering, lounging or bed.

Before You Decide

Confirm the 2-3 years size, the grey colour and the two-piece top-and-bottom format before choosing an offer. If you want a full base layer or sleepwear set, make sure this is the style you need for the child.
