Kids outgrow clothes fast—before you know it, you’re cleaning out their closet and shopping for new shirts, pants, and shoes. While this cycle is unavoidable, finding ways to offset the costs makes it easier on your wallet.
Selling children’s clothing online is quick and convenient. There are dozens of marketplaces where you can list preloved clothing, make extra cash, and clear out space for this season’s new styles.
In this guide, discover the nine best places to sell kids’ clothes and top tips to get the most value for your items.
Thrifting online is the perfect way to clear out your kiddo’s wardrobe, but there are an overwhelming amount of options. Here are the nine best marketplaces to sell used children’s clothing quickly.
ThredUp is the ultimate consignment platform for buying and selling kids’ clothes. It couldn’t be easier—order one of our handy Clean Out Bags (prepaid shipping label included), fill it with your preloved clothes, and send it to us.
Our site is best for people who want a lightning-fast sales process. Experts handle the technical work, so there’s no need to take pictures of your items, write descriptions, or communicate with buyers.
ThredUp carries a huge selection of the most popular kids’ clothing brands, including Mini Boden, Janie and Jack, and Hanna Andersson, so you can easily thrift a few new high-quality items while you sell.
Our platform is also easy to use—manage your sales through the website or our convenient app.
Kidizen is one of the most popular places to sell children’s clothes for cash. Listing items is a little hands-on—you need to set up a profile, take photos, write descriptions—but you can ease the process by hiring a Style Scout. While these associates help you sales, they also take a portion of the proceeds.
A standout feature of Kidizen is the social aspect of their app. This consignment store doubles as a parent-to-parent community, making it a great place to share photos and ask for advice.
Poshmark is a massive online consignment store with over 80 million users. It’s well-known as a buying and selling platform for designer goods and offers a high-quality marketplace for kids’ clothes.
The selling process is straightforward—take photos, upload them to your profile, and write item descriptions. When your clothes sell, print out a prepaid shipping label and send them to their new home.
Poshmark’s cross-listing app tool lets you relist your items on Depop and Mercari in a few taps so more people see your posts.
Depop is an online marketplace with a predominantly younger audience—mainly Gen Z. While this means fewer parents use it, the platform is also less saturated, so your clothing could sell more quickly.
Sellers must take pictures, create listings, and ship the sold items themselves. Depop also offers an app so you can monitor your listings from your devices.
There are no selling fees, but it’s a shame that the price of shipping labels is deducted from your final sale.
eBay is one of the most famous online marketplaces, offering auctions, one-off listings, and licensed brand stores. Its selling process is one of the most complex, requiring users to take photos, write descriptions, set shipping prices, and choose whether they want an auction or a Buy It Now listing.
While this marketplace is complicated, it’s a suitable platform for sellers who want more control over the process. eBay lets you choose payment preferences and even create a returns policy.
Reviews say eBay’s app is more intuitive and user-friendly for sellers rather than buyers, so consider that if you’re looking for a simple platform.
Facebook Marketplace is a platform where users can buy, sell, and trade items. There are shipping options, and this website also helps you connect to relevant buyers in your area for people who enjoy a local experience.
Like eBay, you handle the entire sales process on Facebook Marketplace, including taking photos, writing descriptions, and ensuring the buyer receives the item. However, this means there are no selling fees for local transactions (there is a small cost for shipping items).
Unfortunately, Facebook Marketplace has no dedicated app, so you need to go through Facebook itself.
Mercari is an online consignment store that focuses heavily on its convenient app. For a large global marketplace, it’s a bit less saturated than other stores, so it’s a good place to get noticed.
Selling is straightforward but requires some manual effort. You’ll need to take photos, create listings, and determine a competitive price. Then, you must choose one of two shipping options: sending it yourself or a prepaid shipping label.
Out&Back is an online consignment store focusing solely on outerwear, including hoodies, vests, and gloves. While their selections are limited to one category, their smooth service makes them worth checking out. You simply answer a few questions about your clothes, and you’ll receive an offer straight from the company—accept it, get paid, and Out&Back pays for shipping.
This platform doesn’t offer an app, but since you don’t need to manage a sales process, it’s still easy to use.
Hanna Andersson, one of the most popular kids’ clothing brands, recently launched its very own secondhand marketplace called Hanna-Me-Downs. This is a good choice for anyone obsessed with the brand, as it’s a store specifically for buying and selling Hanna Andersson clothes. Plus, you receive 100% of the sale price when you choose store credit (70% if you opt for cash).
They offer a standard sales process and require the seller to take photos and create a listing, but they lend a hand by recommending prices. It’s a relatively small platform and doesn’t have its own app.

Selling kids’ clothing on platforms like ThredUp is effortless, but you can increase your success and get better value by practicing these five helpful tips.
Always wash clothing before you sell it. This helps you showcase your kids’ items at their best, revealing their true quality and color.
Clean each item thoroughly and carefully, adhering to its specific washing instructions. Ensure everything is wrinkle and odor-free.
Some platforms, like ThredUp and Out&Back, handle the hardest parts of selling, but if you undergo a more manual process, we recommend using some supplies.
Finesse your photography lighting and work against a simple, neutral backdrop to make your pictures more appealing. If you plan on selling clothes often, you might buy a small mannequin to drape clothing off of.
Another great tool is a cross-listing app, which lets you post your items on multiple sites simultaneously. While some selling platforms offer their own apps, there are also many third-party options you can try, including Vendoo and Crosslist.
You can sell kids’ clothing with minor defects and imperfections, but try to tidy them up first.
Take a little time to mend loose threads, remove oil stains, and replace missing buttons. This small step increases your odds of selling and ups your total final price.
Boost your success rate by selling children’s clothing at peak posting times, including relevant seasons, special events, and holidays. A winter jacket might not sell in June, but it’ll be in high demand in November when snow is around the corner.
Consider more niche occasions, too—way more thrifters will be on a treasure hunt around National Thrifting Day on August 17th.
Thrifters love finding complete sets, so bundle your clothes into groups whenever possible. While separates are fine, a matched set of pajamas from popular brands like Mini Boden or Tea Collection will sell at competitive prices.
While there are many options for cleaning out and organizing your kids’ closets, ThredUp offers the smoothest, most effortless experience.
Order a Clean Out Bag, fill it with high-quality children’s clothing (it holds a lot—up to 30 lbs!), and send it back to us with the provided prepaid shipping label. That’s it—no pictures, listings, or negotiations. Just sit back and earn cash or credit so you can buy the next clothes they’ll outgrow.
