A white T-shirt for children might seem like a simple purchase, but the differences between models are noticeable in practice. The wrong size can quickly feel too tight, while a shirt that is too thin may be see-through or less suitable for everyday wear. What's more, age labels and fits aren't always used consistently across different brands.
Pay particular attention to these three common pitfalls:
Below, we've laid out the key buying criteria and some specific options side by side for easy comparison.
In children's clothing, sizes 110, 116 or 122 usually refer to height in centimetres. The Chicco size guides also provide chest, waist and hip measurements. This makes comparing much easier.
Some examples from the available size guides:
The guides vary from product to product. A Chicco T-shirt size 116 and a Chicco T-shirt size 122 are therefore not simply a larger or smaller version; the stated body measurements can differ slightly between styles. If in doubt, measure a well-fitting shirt or check your child's chest measurement.
For adults, Nike uses a different sizing system. The Nike Sportswear Club T-shirt in size L is intended, according to the product information, for a chest measurement of 104–112 cm. Size XL is listed for 112–123 cm. If you're between two sizes, Nike suggests choosing the smaller size for a closer fit or the larger size for more room. This is a brand recommendation, not a guarantee of the same fit for every body shape.
A cotton T-shirt for children is often chosen for everyday wear, for example under a jumper, for playing or as a simple wardrobe staple. The available Chicco styles for boys list 100% cotton. The Nike Sportswear Club T-shirt is also described as being made from 100% cotton.
However, there are more points to consider:
The fabric composition tells you about the fibres, but not automatically about the thickness, stretch or how the shirt will hang after several washes. So also check the product photos, available sizes and care information.
A long-sleeved T-shirt for children is practical as an extra layer in cooler seasons or under a coat. The Chicco long-sleeved tops are available in sizes from baby sizes up to larger children's sizes, including 116, 122 and 128.
A short-sleeved T-shirt for boys is better suited to warmer days, wearing indoors or as a base layer. The range includes Chicco styles in sizes such as 56, 62, 74, 80 and 92. For a baby, a short sleeve can also be easier to combine with a cardigan.
A white vest top for a boy has no sleeves and can work well as a lightweight layer. The Chicco vest top in size 122 is described as being for boys, comes in white and is made from 100% cotton. Just be sure to check whether you're looking for a vest top or a short-sleeved style; these terms are sometimes used interchangeably in search results.

We've put together a full, up-to-date list of products that fully meet these strict selection criteria and comply with current European safety regulations.
First, look at the child's height. In the Chicco guides, size 116 is linked to around 6 years old and size 122 to around 7 years old. Also check the chest, waist and hip measurements. Age is only a guideline.
The Chicco and Nike styles mentioned list 100% cotton. This can be a practical choice for an everyday shirt, but how it feels to wear also depends on the thickness, fit and finish. Always follow the care label to best preserve the shape and colour.
Choose a long-sleeved T-shirt for children if you want extra coverage or a layer under a coat. A short-sleeved style suits warmer weather and everyday indoor wear. A vest top is sleeveless and therefore best when you want less fabric around the arms. Always check the product type and size guide before ordering.
