Buying children’s clothing: how to choose practical, true-to-size clothes for every age

Buying children’s clothing online seems easy, until a shirt loses its shape after a few washes, a hoodie is too tight to pull over your child’s head or the size does not match your child’s age. Marketing copy often focuses on colour, brand and appearance. For everyday use, other features are more important.

This guide helps you compare children’s clothing based on size, material, fit and use. That way, you can find baby clothes, long-sleeve T-shirts, children’s hoodies, children’s sweatshirts and complete outfits for children from 0 months to 16 years more easily.

Three common pitfalls when buying children’s clothing

1. Relying only on age

Age labels such as 3–4 years or 9 months are only a guide. Children grow at different rates, and clothing sizes can vary between brands. For example, a Chicco shirt in size 116 may be designed for different body measurements from a sweatshirt by another brand in the same size.

Always check:

• Your child’s height in centimetres.
• Chest, waist and hip measurements where available.
• Whether the size guide lists the garment measurements or the wearer’s body measurements.
• The amount of room for a nappy in baby clothes and baby bodysuits.

2. Assuming all cotton has the same quality

Cotton can feel comfortable, but the cotton percentage and the addition of elastane affect how the garment performs. According to the product information, a Chicco two-piece children’s set with a T-shirt and shorts consists of 95% cotton and 5% elastane. This can provide extra freedom of movement.

Other products list 100% cotton, while Tommy Hilfiger describes various models as made from organic cotton. According to Tommy Hilfiger’s product information, these models use organic cotton and have independent certification. Always check the current product specifications and care label before buying; a general brand claim does not automatically apply to every garment.

3. Overlooking the shape and details

An attractive design is not always practical. When choosing children’s clothing, look out for:

• Ribbed trims on the sleeves, neckline and hem.
• A neckline that provides enough room.
• A hood that does not feel heavy or stiff.
• A pocket that does not pull unnecessarily at the front.
• Fastenings on baby bodysuits that make changing easier.
• Care instructions that fit into your everyday routine.

Dark clothing can make stains less noticeable, while white or light-coloured cotton needs more frequent care. Choose the colour with practicality in mind too.

The key specifications to compare

Sizes 56 to 152: measure first, then order

The range includes children’s sizes from size 56 to 152. Some Chicco size guides run from 0 months and size 44 up to 12 years and size 152. Tommy Hilfiger sizes include age groups such as 3–4 years, EU size 98, through to 15–16 years, EU size 152.

Measure your child while they are wearing thin clothing:

1. Measure their height standing upright, from the crown of the head to the feet.
2. Measure their chest at the fullest point.
3. Measure their waist without pulling the tape measure tightly.
4. Compare the measurements with the specific table on the product page.

Do not automatically buy a size larger “to allow for growth”. A little extra room can be practical in a long-sleeve T-shirt, but sleeves that are too long and a wide neckline can reduce comfort.

Material: cotton, elastane and organic cotton

Cotton children’s clothing is a popular choice for shirts, bodysuits and sets. Elastane can provide extra stretch, but the material composition still determines how the garment feels and how it should be cared for.

When choosing organic cotton children’s clothing, read the product information carefully. The Tommy Hilfiger Essential Hoodie and Essential Sweatshirt are described in the supplied product information as being made from organic cotton. According to Tommy Hilfiger’s own product information, these models are intended for everyday and casual wear. This says nothing about how every child will find the fit, so always check the size guide.

Clothing type: choose according to when it will be worn

• Baby bodysuit: useful as a base layer and for babies who move around a lot. Check the fastening and the fit around the nappy.
• Long-sleeve T-shirt for children: suitable for layering, school and changeable weather.
• Children’s hoodie: practical outdoors and on cooler days; check the hood, pocket and ribbed trims.
• Children’s sweatshirt: often easier to wear under a coat than a hoodie.
• Children’s set with T-shirt and shorts: a quick outfit for warm days.
• Gender-neutral children’s clothing: focus mainly on colour, fit and size rather than the intended audience.

Caring for children’s clothing and extending its lifespan

How long clothing lasts depends on the fabric, washing and how quickly your child grows. Always follow the care label. The product information for the Chicco and Tommy Hilfiger models mentioned refers to the label for washing temperature, drying, ironing and any professional cleaning.

Practical habits can help:

• Wash clothes inside out if you want to protect the colour and prints.
• Use the temperature stated on the label rather than automatically choosing the highest setting.
• Check seams, trims and fastenings before using a garment again.
• Store baby clothes sorted by size so that smaller sizes are not left unused unnecessarily.
• Keep a second version of frequently worn shirts or bodysuits.

Frequently asked questions about children’s clothing

What size children’s clothing do I need?

First measure your child’s height and compare it with the brand’s size guide. Size 56 usually refers to a baby measuring approximately 56 centimetres, while size 152 is available for older children. Age is only an indication.

Is organic cotton children’s clothing always softer?

Not necessarily. How a garment feels also depends on the weave, finish and fit. Check the exact composition and product information. According to Tommy Hilfiger’s own product information, certain hoodies and sweatshirts are made from organic cotton.

Which children’s clothing is practical for everyday wear?

For babies, baby bodysuits and cotton layers are practical. For toddlers and school-age children, a long-sleeve T-shirt, children’s sweatshirt or children’s hoodie is easy to combine with other clothes. A children’s set with a T-shirt and shorts is ideal when you want to put together a complete outfit quickly.
