Choosing children’s clothing without making a mistake: a practical guide for babies, toddlers and children

Children’s clothing needs to stand up to daily movement, washing and unexpected stains. Yet when shopping online, it’s not always clear whether a garment will suit the purpose you’re buying it for. A nice photo or a well-known brand name tells you very little about sizing, fabric and care.

Most buying mistakes come down to three common pitfalls:

  • Choosing a size based only on age: children don’t all grow according to the same chart. A garment labelled “6 months” can fit differently to a size 62.
  • Not checking the material: “soft” or “comfortable” are vague terms. Instead, look at the fibre composition, such as 100% cotton or 95% cotton with 5% elastane.
  • Skipping the care instructions: a garment that requires delicate washing may not be as practical for everyday use as a machine-washable alternative.

What should you look for in children’s clothing?

1. Check the size in centimetres

For baby and toddler clothing, the length in centimetres is often a more reliable guide than age. In the Chicco sizing system, for example, the range runs from size 44 for newborns up to size 152 for children around 12 years old. The stated age is only an indication.

If you’re unsure, measure:

  • your child’s height;
  • their chest circumference;
  • the waist and hips, if you’re buying trousers or sets;
  • the inside leg length for older children.

Also be aware of differences between brands. A Chicco children’s long-sleeve shirt in size 128 may fit differently to a Tommy Hilfiger children’s sweater in the same size. So always check the size guide on the product page.

2. Look beyond the word “cotton”

Cotton children’s clothing is often chosen for its natural fibre. However, the composition matters. A shirt made from 100% cotton has different properties to a garment made from 95% cotton and 5% elastane. Elastane can offer extra freedom of movement, while a blended fabric may react differently to washing.

With organic cotton children’s clothing, it’s wise to check the product information for the exact wording and certification. The Tommy Hilfiger product descriptions in this range state 100% organic cotton and refer to certified organic cotton. That is a product claim from the brand and should not be confused with a general guarantee for every garment from the same brand.

For babies, a cotton baby bodysuit with a little elastane can be practical, as it moves more easily with your child. For newborns, also check that seams, fastenings and labels don’t feel unnecessarily hard or irritating.

3. Choose the garment type to suit the use

A children’s long-sleeve T-shirt works well as a layer in spring and autumn, or under a cardigan. A children’s hoodie offers more coverage, but may be less practical for a baby because of the hood and thicker fabric. A children’s round-neck sweater is often easier to combine with a coat.

When buying, think about everyday use:

  • For nursery or school: choose styles that are easy to put on and take off.
  • For outdoor play: look for freedom of movement and sturdy cuffs.
  • For babies: check the fastening and the size around the neck.
  • For a shared wardrobe: gender-neutral children’s clothing in grey, navy, white or natural tones is easy to mix and match.
  • For holidays or sleepovers: a children’s clothing set can save time when putting outfits together.

Frequently asked questions about children’s clothing

What size of children’s clothing do I need?

First, measure your child’s height and compare it with the brand’s size guide. Size 62 usually corresponds to a baby around 62 centimetres tall, while size 152 is used for older children. Age is only a guideline; body measurements are more decisive.

Is cotton suitable for baby and toddler clothing?

Cotton is commonly used for baby and toddler clothing. However, do check the full composition and the washing instructions. A product made from 100% cotton is different from a fabric containing cotton and elastane. For a baby bodysuit, the fastening, neckline and seams are also important for practical everyday use.

How long does children’s clothing last?

The lifespan depends on your child’s growth rate, how often the garment is worn, the fabric and how it’s cared for. Wash according to the label, avoid too high a temperature when that’s not recommended, and check whether the garment can go in the tumble dryer. A slightly roomier fit can last longer, but clothes that are too big can be uncomfortable to wear.
