What to Compare Before Buying
- Size: The set is marked 3-4 years, so check that against the child’s current size before choosing.
- Use as a base layer: It is presented for layering under regular clothes, so consider whether you want a thinner underlayer or a warmer home set.
- Set format: This is a top and bottom set, so check that you want both pieces together rather than a single item.
- Fabric feel: The fabric is described as soft, plush and breathable, which may matter if comfort is a priority.
Before You Decide
Confirm the 3-4 years size, the blue colour and the fact that this is a two-piece thermal top and bottom set. If the child needs a different size range, a different option should be chosen.
