How do I list the size of children's clothes?

Use the age range on the label, like 2-3 years or 6-9 months, because that is what parents filter by. Add a measurement or a note if it comes up small or large.

How to sell kids' and baby clothes in the UK

Q: Is it better to sell kids' clothes in bundles?

For everyday basics, yes: a bundle of vests, sleepsuits or leggings in one size sells far better than single items worth a pound or two. Branded, new-with-tags or special pieces like coats and party dresses are worth listing on their own.

Q: Where is the best place to sell children's clothes in the UK?

Vinted is the go-to for kids' clothes and bundles, with no selling fee for sellers. Facebook Marketplace and local selling groups work well for big bundles and collection, and eBay suits branded or new-with-tags items.

Q: Can I sell a second-hand car seat?

It's best not to. Safety organisations advise against buying second-hand car seats because you cannot be sure they have not been in an accident, and some marketplaces restrict them. Recycle it instead.

Children outgrow clothes long before they wear them out, so most families have bags of them in the loft. Other parents are actively looking for exactly that. Here's how to turn them into money without spending every evening listing.

Sort by size first

Parents shop by age range, so sort everything into piles by the label size: 0-3 months, 3-6 months, 6-9 months, and so on up through 2-3 years, 3-4 years and beyond. Within each pile, split out boys', girls' and neutral if you want, and pull out anything branded, new with tags or special.

Wash and fold everything before you photograph it. It's the single biggest difference between a bundle that sells and one that sits.

Bundles or single items?

Bundle the basics. A single vest or pair of leggings is worth very little and costs about as much to post as it sells for. Ten sleepsuits in 3-6 months, or a "girls' 4-5 years autumn bundle" of tops and leggings, is something a parent will happily buy in one go.

List the good stuff on its own: coats and snowsuits, branded pieces, new-with-tags items, party and occasion wear, and anything a parent would search for by name.

What sells best

Winter coats, snowsuits and puddle suits (list them in September and October).
Branded kidswear and well-known high street ranges in good condition.
School uniform, especially in July and August. See what sells when.
Christmas jumpers and outfits, from late October.
Fancy dress costumes, before Halloween and World Book Day.
Baby bundles in newborn to 12 months, where items barely get worn.

Where to sell

Vinted is the go-to for kids' clothes and bundles, and sellers pay no selling fee.
Facebook Marketplace and local parents' groups suit big bundles, bulky items and collection.
eBay for branded or new-with-tags pieces and larger mixed lots.

Writing the listing

Put the age range and what's included in the title. Parents search "girls bundle 2-3 years", not "lovely bits".

Example listing Girls' clothes bundle, age 2-3 years, 12 items, autumn 12 items in age 2-3 years from a smoke-free home: 4 long-sleeve tops, 3 pairs of leggings, 2 dresses, 2 cardigans, 1 pair of dungarees. Mostly high street brands. Good condition, all washed; one top has a small mark (photo 6). Posted within 2 working days.

List everything that's in a bundle, and photograph the whole lot laid out together plus a few close-ups. Call out any marks in the description and a photo.

Pricing

Check sold listings on Vinted or eBay for similar bundles in the same age range. As a rough guide, everyday bundles sell for a modest amount per item, while branded and new-with-tags pieces hold value much better. Price a little higher than your minimum: parents often send offers, especially on bundles.

For a step-by-step method, see how to price items on Vinted.

What not to sell

Second-hand car seats: safety organisations advise against them because you can't be sure they haven't been in an accident. Recycle instead.
Anything recalled or with damaged fastenings, loose buttons or worn-through fabric.
Heavily stained or bobbled basics: textile recycling banks are a better home.
