17 Shops Selling Used Kids Clothes Online & Helping Your Gremlins Grow Up Green
In an age where sustainability and budget-consciousness are gaining momentum, the market for used kids’ clothes is growing faster than our kids themselves.
Unbelievably, 37% of families wish they had more children, but one of the most common discussions about having more children is finances.
Even with their cute dimples and tiny feet, kids cost a pretty penny!
Especially because those tiny bodies do not stay tiny long.
Children grow so fast (yes, even out of your hand-knit sweater!), so from a sustainability standpoint, it only makes sense to pass on, share, sell, and skip brand new.
Here at SJ, we love to love things twice, so we wanted to take one thing off your parenting to-do list by apply our know-how of second hand stores to bring you some dealing specifically in second hand kids’ clothes.
Everything we recommend to you on Sustainable Jungle is independently researched and we ask all brands to confirm their claims. To avoid waste, we test products on an as needed basis.

Why Buy Second Hand Kids’ Clothes Online?
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 kids’ used 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.
Final Thoughts On Where To Buy Used Kids’ Clothes Online
Raising kiddos can be a lot of weight to carry, so companies that sell gently-used kids’ clothing and used baby gear at a fair price are a 10/10 in our books.
Among the laundry list of to-do’s, finding the perfect outfit for your child should bring you joy, instead of overwhelm.
Shop for tomorrow’s styles from the comfort of your own home while your baby sleeps on their organic baby planet or crawls around on their non-toxic play mat.
Plus, you can feel extra fulfilled knowing you helped saved all those toys and tees from turning into trash.
And when your kiddos grow out of them, be sure to donate or resell them through online consignment shops to keep the cycle moving and help out other parents looking for more eco-friendly outfits for their kids.
Speaking of keeping things moving…
