13 Shops Selling Used Kids & Babies Clothes Online

Even with their cute dimples and tiny feet, kids and babies cost money. After all, tiny bodies do not stay tiny for long.

So from a sustainability standpoint, it makes a lot of sense to pass on, share, sell, and skip new clothes.

Here at SJ, we love to love things twice, so we wanted to take one thing off your parenting to-do list by applying our know-how of second hand stores.

Specifically those that deal in second hand kids’ and babies’ clothes. Saving you cash while saving the planet in the process.

Who says prelove kids’ clothes can’t be made from premium responsible fabrics?

Combining a number of well known brands, thredUP offers pre-loved kids’ clothing for the tiniest of tots all the way up to XL youth.

With a supplied bag and pre-paid label, thredUP receives the items you’ve simply placed in the bag and shipped back and ensures they undergo quality inspection before placing them for sale.

That’s right: no photographing items or creating individual listings. They do it all for you—as long as you’re okay with the fact that not all your sent item may meet their guidelines (in which case they donate them).

You’ll get paid whenever one of your kids’ consignments online sells.

Beyond regular moms and dads looking to sell gently-used kids’ clothes, thredUP offers Resale-as-a-Service for brands looking into the resale market without the ability to create an entire platform of their own.

If you have bags of cute, clean wardrobes made up of your favorite brands that your little one juuuuust outgrew, you’re not alone. Now you’re hunting for next season’s clothing without the hefty price tag of a full-dresser replacement.

Putting a unique spin on kids’ consignments online, Swoondle is your ticket to access children’s clothing, using those bags of cute clothing you already own.

How does it work?

When Swoondle was created, founder Jennifer wanted to make it possible to shop using a trade in credit for the clothes you send in.

After your bag arrives at Swoondle, it is assessed and given a “level” (1-5) corresponding to a credit system you can use on the site to purchase your kids clothing for the next size up or season.

Customers buying power comes from their own donated clothing. Or, you can choose to simply shop their online items and pay cash.

Swoondle accepts and sells used children’s clothes, shoes, outwear, and costumes in sizes newborn to 14 years.

Because their stock comes directly from parents and is ever revolving, you never know what you might find. We’ve found everything from basic onesies to luxury items like a swimsuit cover-up from Oscar De L Renta (for under $40!).

If you need to buy used baby clothes in the UK, Katie’s Kids Clothes is the website for you.

As a young mum of three littles, Katie wanted to make picking up (and dropping off) mountains of kids clothing in good condition simple for families just like hers.

You can sell to Katie’s Kids Clothes by weighing your items, photographing them, and sending that info to Katie. She’ll give sellers a price based on the weight and size of the clothing and will pay for clothes to be picked up and delivered via courier.

The items are checked by Katie, and you get paid.

Girls and boys clothing, costumes, school uniforms, and a festive selection of Christmas outfits are a few of the kids’ clothes used you’ll find.

Saving money alone isn’t the only reason to buy second hand kids’ clothes as opposed to brand new.

As we all know, the fashion industry creates an unbelievable amount of waste (even when you’re only outfitting tiny bodies).

Up to 183 million pieces of children’s clothes are tossed in the trash each year, and it’s not because they’ve reached the end of their wearability.

Children grow at a rate we shorter adults could only dream of.

With an average 2.5 inch growth spurt per year, many parents struggle to keep up with the sheer volume of clothes they’re purchasing, selling, exchanging, and trading to meet their kid’s needs. Perfectly good clothing can wind up in the trash during a seasonal house declutter.

But thanks to the best kids’ consignment stores, resale shops and online vintage shops, it’s easier than ever to replenish your child’s wardrobe at a fraction of the price and carbon footprint.

Secondhand fashion (for adults and kids alike) = sustainable fashion, after all.
