How to Spot Quality in Children's Clothes (Price Isn't the Signal)

To tell quality in kids' clothes, check five things before the price tag. Read the fibre content, feel how dense the fabric is, look at the seams on the inside, test the buttons and poppers, and ask whether it could survive a second child. Good clothes show their quality in fibre and stitching, at any price.

A high price feels like a promise. Sometimes it's paying for a logo or an advertising budget, and the seams inside tell a different story.

We think real luxury in children's clothes is fibre and stitching: things made well enough to be handed down, whatever they cost.

So here's how to tell quality kids' clothes in about 10 seconds, in a shop or the moment a parcel arrives.

How can you tell quality in kids' clothes in 10 seconds?

1. Read the label. Fibre first, before the price.
2. Hold it up to the light. Denser fabric lets less light through.
3. Turn it inside out. Look at the seams and check for loose threads.
4. Gently stretch the cuffs and neckline. Good ribbing springs back.
5. Tug a button or popper. It should feel firmly attached.
6. Picture the second child. Would it still look good after a year of wear?

Nothing on this list needs a price tag or a logo.

Why is fibre content the first quality check?

A garment can only be as good as what it's made from. In the UK, textile labels must show the fibre content, so the answer is always there.

Read it the way you'd read an ingredients list. A single natural fibre is easy to understand. A blend can be good too, as long as each part has a job, like a little cashmere for warmth or a little elastane to help socks and cuffs keep their shape.

If the label says one thing and the price suggests another, trust the label.

What does fabric weight (GSM) tell you?

GSM stands for grams per square metre. A higher number usually means a thicker, denser fabric.

Not every brand lists it, so use your hands. Denser fabric feels fuller, is harder to see through and holds its shape when you let go. When a brand does list it, like Wildgreen with its 340GSM sweaters, it gives you something useful to compare.

Heavier isn't always better. A summer romper should be light. What matters is that the fabric feels substantial for the job it's doing.

What should seams and stitching look like?

Turn the garment inside out. This is where quality, or the lack of it, shows.

• Even stitches: straight lines with no loose or skipped threads.
• Flat seams: no puckering or twisting along the side seams.
• Neat edges: raw edges finished inside so they won't fray in the wash.
• Extra strength where it's needed: knee patches, elbow patches and reinforced heels, where children wear through first.
• Comfortable placement: seams sitting where they won't rub, like a sock seam on top of the foot.
• Crisp prints: a print that sits sharp and even on the fabric.

What about buttons, poppers and zips?

Fastenings get the most wear, and they're where cheap construction often gives up first.

• Give each button or popper a gentle tug. It should feel secure.
• Check the poppers are where you need them, such as at the bottom for nappy changes.
• Look for easy necklines, like buttons at the back of the neck, so dressing isn't a battle.

Will it pass the hand-me-down test?

This is our favourite check. If it could go on to a sibling, a cousin or a friend, it's well made.

A cheap piece that passes can outlast an expensive one that doesn't. And an expensive piece that lasts through three children starts to look like very good value.

How we vet this at KIDDYKIND

The KIDDYKIND Test asks what something is made of, where it's made, why it's designed the way it is, whether the people who made it were paid fairly, whether it's kinder to children and the planet, and whether it's actually useful.

Price isn't one of the questions.

For clothing, "why is it designed this way?" tells us a lot. Knee patches exist because crawlers crawl. A roll-down cuff exists because children grow. That's how a £17 pair of leggings and a £148 jumper can earn their place for the same reasons.

Some of our suggestions

A few pieces from across the KIDDYKIND brands that pass the 10-second check:

• Delft Sweater by Wildgreen. 340GSM organic cotton jersey in a relaxed boxy fit, with stretchy ribbed neck and cuffs.
• Chocolate Ribbed Leggings by Wildgreen. 260GSM ribbed organic cotton with an elasticated waist, from 0–3 months to 4–5 years.
• Cable Popcorn Jumper, Avocado by MIKA & MILO. The pattern is the stitch itself, in 95% organic cotton and 5% cashmere, and it's mendable for life by the same hands that made it.
• Lili Short Ribbed Socks with Lace by MIKA & MILO. Made by Collégien, a family-run French sock maker founded in 1947, with a reinforced heel and the seam placed on top of the foot.

FAQs

Are expensive kids' clothes better quality?

Sometimes, but the price alone won't tell you. Check the fibre, fabric weight, seams and fastenings.

What are the best quality kids' clothes in the UK?

The best ones tell you exactly what they're made of and show their construction when you turn them inside out. Look for clear fibre content, strong seams and details made for real childhood, like knee patches and room to grow.

How can I tell if kids' clothes will last?

Look for dense fabric, flat and even seams, secure fastenings and extra strength at the knees, elbows and heels. Then ask whether it could be handed down.

What does GSM mean on clothing?

Grams per square metre. A higher number usually means a thicker, denser fabric.

Is organic cotton better quality than regular cotton?

Organic describes how the cotton was grown. Quality also depends on how the fabric is knitted or woven and how the garment is sewn, so check both.

Buy fewer things, made well, and let them be handed on. Our Jumpers & Sweatshirts collection is a good place to try the 10-second check.
