Baby clothes labels: how to read fabric composition
Part of our newborn baby care guide

When you choose clothing for your baby, the real clue to quality isn't the price or the brand: it's the label. That little strip of fabric sewn onto the side or the collar holds all the information that truly matters — composition, origin, certifications, washing instructions. Learning to read it in 30 seconds spares you bad purchases and protects your newborn's delicate skin.

Why the label matters so much for a newborn

A baby's skin is thinner than an adult's: in babies aged 3 to 24 months the outermost layer, the stratum corneum, measured about 30% thinner and the epidermis about 20% thinner. In a healthy full-term newborn the skin barrier already works at birth, but it keeps maturing over the first years. Everything that touches the skin for hours — fibres, dyes, finishing residues — matters: Nationwide Children's Hospital lists dyes used in clothing among the allergens that cause contact dermatitis in children.

The label is also the only thing on the garment that federal law forces the seller to get right. Under the Textile Fiber Products Identification Act the FTC requires the generic fibre names and percentages by weight in descending order, the country where the product was processed or manufactured, and the maker's business name or RN number. A separate FTC rule, the Care Labeling Rule (16 CFR 423), requires care instructions on a label attached permanently and securely and legible for the useful life of the garment. Knowing how to read all of that is the first form of prevention.

1. Composition: which fibres to look for (and which to avoid)

This is the most important piece of information. Composition is expressed in fibre percentages. For the first months, aim for natural, breathable and soft fabrics.

Recommended fibres for a newborn

  • 100% cotton — the staple of baby clothing. Breathable and soft, it absorbs sweat.
  • Certified organic cotton — the best for sensitive skin. Look for the GOTS wording (see below).
  • Merino wool — for the cold months: fine merino is much softer than traditional wool. Pricey, but useful for winter layers.
  • “Bamboo” — very soft, but read the label: the FTC notes that most, if not all, “bamboo” textiles are really rayon, with no trace of the original plant, and must be labelled as rayon or “rayon made from bamboo”. A claim that the fabric keeps bamboo's antimicrobial properties needs proof the seller can show.
  • Linen — cool and breathable for summer, even if a bit stiffer: better in a blend with cotton.

Fibres to limit or avoid in direct contact with the skin

  • Polyester, acrylic, nylon (100%) — synthetic fibres that breathe poorly and trap sweat. A little spandex to add stretch to cuffs is fine; a polyester bodysuit against the skin is a different thing.
  • Blends with a large synthetic share in direct contact with the skin, especially in summer, when the baby sweats more.

Rule of thumb: there is no official threshold, but for garments in direct contact with the skin (bodysuits, sleepers, pajamas) choose ones that are mostly or entirely cotton. For outer layers (jackets, snowsuits, coats) composition matters less, because they don't touch the skin.

2. Country of origin: what the “Made in” really tells you

The “Made in” is the line shoppers read first and over-interpret most. In the US it carries less weight than people assume, for a simple reason: federal children's-product rules attach to what is sold here, not to where it was sewn.

  • The chemical limits are the same either way. A children's garment offered for sale in the US has to meet the CPSIA limits on lead and phthalates, and the CPSC flammability standards for children's sleepwear (16 CFR 1615 for sizes 0–6X, 1616 for sizes 7–14), whether it was made in North Carolina, Portugal or Bangladesh. Importers carry the same certification duty as domestic manufacturers.
  • What origin does tell you is something about supply-chain length and traceability, and sometimes about a brand's ability to audit its own factories. It tells you nothing about the dyes actually used on the garment in your hand.
  • Where origin is genuinely useful is as a cross-check on the rest of the label: a garment whose origin, fibre percentages and RN number are all clearly declared is from a seller taking the FTC rules seriously. Vague labelling is the warning sign, not a particular country.

In practice: a garment with a GOTS or OEKO-TEX certification you can look up tells you more about chemical testing than the “Made in” line on an uncertified one, whatever the country. Read the certification, not the flag.

3. The baby clothing certifications that matter

They are the most reliable way to know a garment has been tested for safety. Look for these marks on the label or on the tag:

  • OEKO-TEX® STANDARD 100 — every thread, button and accessory of a certified article is tested against a list of over 1,000 harmful substances. Product Class 1 covers articles for babies and children up to 3 years and has the strictest limit values.
  • GOTS (Global Organic Textile Standard) — certifies that the fibre is organic and that processing (dyeing, finishing) meets its environmental and chemical criteria. The reference for organic cotton and wool.
  • Made in Green by OEKO-TEX® — combines chemical safety and sustainable, traceable production.

A label is only worth its number: an OEKO-TEX label number can be checked in OEKO-TEX Label Check, and a GOTS label names its certification body and a certification number you can look up in the GOTS public database.

4. Care instructions: small but decisive

One thing to know before you squint at a pictogram: US care labels are usually written in words. The FTC rule lets a manufacturer use the ASTM D5489 care symbols in place of words, but the ISO symbols used on European labels are not currently permitted here, so the symbol set you may have seen abroad is not the one you will find in a US store. For baby clothing, two rules above all:

  • “Machine wash warm” or just “Machine wash” — under the rule, warm means an initial water temperature of 87-111 °F, hot 112-145 °F, and a label with no temperature at all means hot water up to 145 °F will not harm the garment. A label that says cold wash only, or hand wash, is less practical in real life with a newborn, whatever the fabric is.
  • “Only non-chlorine bleach, when needed” or “No bleach” — the rule only requires a bleach instruction when some bleaches would damage the garment, so the presence of that line is itself information. Chlorine bleach is the wrong tool on baby clothes in any case.

Important: always wash new garments before first use, even certified ones. It removes processing residues, sizing and dust caused by transport and store display.

5. Construction details to check on the label and on the garment

  • Flat, soft seams — stiff seams rub. Quality garments have flat seams, especially on shoulders and crotch.
  • Printed label, not sewn — more and more brands print the information directly onto the inner fabric, to avoid the annoying rubbing of the label on the back of the neck. A nice sign of attention to detail.
  • Sturdy, well-attached snaps — tug them. Children's clothing and buttons are exempt from the CPSC small parts rule (16 CFR 1501.3), so no federal test checks how firmly a snap is attached: a snap that pulls off ends up in a baby's hand, and then in their mouth.
  • No hood or neck drawstrings — the CPSC has determined that hood and neck drawstrings on children's upper outerwear in sizes 2T to 12 are a strangulation hazard and a substantial product hazard under 16 CFR part 1120, and that waist or bottom drawstrings in sizes 2T to 16 are too when they extend more than three inches outside the channel or end in a toggle or knot. Between 1985 and 2019 the agency documented 26 deaths and 73 nonfatal incidents, most often on playground slides.

Quick label checklist before you buy baby clothes

Flip the label over and in 30 seconds check:

  • ✅ Composition: mostly or entirely cotton (or fine merino in winter) for garments in contact with the skin.
  • ✅ Certification: OEKO-TEX STANDARD 100 or GOTS, with a number you can look up.
  • ✅ Label completeness: fibre percentages, country of origin and RN number all declared.
  • ✅ Care: machine washable warm, not cold-or-hand-wash only.
  • ✅ Flat seams, no hood or neck drawstrings, sturdy snaps.

Reading a baby clothing label: the short version

The label is the garment's ID card: it tells you what it's made of, where it comes from and how to care for it. For a newborn, reading it isn't fussiness, it's prevention. Aim for mostly or entirely cotton, look for an OEKO-TEX STANDARD 100 or GOTS certification you can verify, and remember that the country of origin matters less than a good independent certification. Thirty seconds of reading save you waste and garments that are never worn.

Frequently asked questions about baby clothing labels

Why does the label matter so much for a newborn?

Because a baby's skin is thinner: the outermost layer, the stratum corneum, is about 30% thinner than an adult's and the epidermis about 20% thinner (measured in babies aged 3 to 24 months). In a healthy full-term newborn the skin barrier already works at birth, but it keeps maturing over the first years. Nationwide Children's Hospital lists dyes used in clothing among the allergens that cause contact dermatitis in children. The label is the only document that, by law, states fibre content and care instructions.

Which fibres are best for a newborn's skin?

Cotton — ideally certified organic — is the usual choice: breathable, soft, it absorbs sweat. Fine merino wool works for cold months, and linen suits summer, best blended with cotton. "Bamboo" fabrics are almost always rayon: under FTC rules they must be labelled as rayon or "rayon made from bamboo", and claims that they keep the plant's antimicrobial properties need proof.

Which fibres should be avoided in direct contact with the skin?

Garments made entirely of polyester, acrylic or nylon, because they breathe poorly and trap sweat, especially in summer. A small share of spandex to add stretch to cuffs and waistbands is fine: the label tells you exactly how much, because the FTC requires fibre percentages by weight.

What's the rule of thumb for the cotton percentage to look for?

There is no official threshold. For garments in direct contact with the skin — bodysuits, sleepers, pajamas — choose ones that are mostly or entirely cotton, with at most a little spandex for stretch. For outer layers, like jackets and snowsuits, composition matters less because they don't touch the skin.

Does "Made in" alone guarantee a garment is safe?

No, and in the US it matters less than people assume. Federal rules attach to what is sold here, not to where it was sewn: the CPSIA lead and phthalate limits, the CPSC sleepwear flammability standards and the drawstring rule apply to an imported garment exactly as they do to a domestic one. A garment with a GOTS or OEKO-TEX certification you can look up tells you more about chemical testing than any "Made in" line on an uncertified one. Read the certification, not the flag.

Which certifications should you look for on the label?

OEKO-TEX® STANDARD 100, whose Product Class 1 covers articles for babies and children up to 3 years and has the strictest limit values; GOTS (Global Organic Textile Standard), which certifies organic fibre and the processing chain; and MADE IN GREEN by OEKO-TEX®. Each label carries a number you can look up in the certifier’s public database.
