How to choose the right second hand size for children

Comment bien choisir la taille en seconde main pour enfant

Size is just an indicator

The size indicated on the label is only a base. It corresponds to an average, but each child is different. Second-hand, a garment may have seen minimal or heavy use, which may slightly transform its original shape.

To remember: never rely exclusively on the number entered.

Rely on age, but especially on morphology

Age is a good starting point (2 years, 4 years, 6 years), but it is insufficient alone. Two children of the same age may require very different sizes.

When buying second-hand, it is better:

  • prioritize comfort over perfect fit
  • slightly anticipate growth, particularly for sweaters, jackets and coats

Consider brands

Not all brands cut the same way. Some offer generous cuts, others more narrow. Pants size 4 years old may be suitable for a 3 year old child at one store and a 5 year old child at another.

The importance of the condition of the clothing

The condition directly influences the choice of size. A lightly worn piece retains its original shape, while an often-used piece may have softened. Slightly softened jeans sometimes offer more comfort than a new rigid model.

Measuring a piece of clothing your child already wears

Simple but very reliable strategy: take a piece of clothing that fits your child well and measure it.

Note:

  • total length
  • the width at the waist
  • sleeve length

These measurements are much more reliable than a label indication, and comparison with the measurements provided by the seller validates the purchase.

Adapt the choice according to the type of clothing

  • Tops: you can oversize slightly (sweaters, sweatshirts, t-shirts)
  • Trousers: be careful about length and size, especially without adjustment
  • Dresses: more flexibility, wearable longer or as a tunic
  • Coats and jackets: anticipating makes it easier to wear over several seasons

In summary

Choosing the right second-hand size does not require any particular skill, but a little attention: observing the child's morphology, taking into account the brands, the condition and the type of item helps to avoid the majority of disappointments.
