If you’ve been wondering “where can I sell kids clothes online?", there are several online platforms that make it easy to turn outgrown clothing into extra cash. ThredUp works well if you want to send in clothes and let the company handle all the work. Poshmark and Mercari are popular resale apps for selling kids clothes. eBay offers a huge buyer audience, while Depop attracts trend-focused shoppers. Facebook Marketplace is great for local bundles, and Etsy can work for handmade or vintage pieces.
There are also smaller platforms like (re)PLAE and Kidgearmarket. Many sellers use two or three platforms at once to reach more buyers and sell items faster.
Why Selling Kids Clothes Online Works Well
Selling kids clothes online still works for a simple reason: children outgrow clothing quickly. Many families go through multiple sizes every year, which creates a steady supply of gently used clothing in the resale market. At the same time, other parents are actively looking for affordable options and often look to secondhand clothing.
Demand is especially high for well-known kids brands and clothing in good condition. Parents look for items that still have plenty of life left, but cost much less than buying new. Because of this, some resellers focus on grouping items into bundles or lots, such as “6–12 month summer bundle” or “boys size 5 fall lot.” These can sell faster than individual items because they give buyers more value and lower shipping costs.
Prices will vary depending on the brand and condition, but most used kids clothing sells for around $5 to $25 per item when sold individually. Bundles often sell for more, depending on the number of pieces and brands included.

Tips for Selling Kids Clothes Online Successfully
Selling kids clothes online is simple, but a few small details can help listings sell faster and avoid common issues.
- Photograph items in natural light and include clear pictures of the size tag, brand tag, and condition.
- Sell items in bundles or lots, such as “6–12 month summer lot” or “girls size 5 fall bundle.” Bundles can sell faster and help offset shipping costs.
- Price items competitively by checking recent sold listings on platforms like eBay.
- Mention the brand, size, and condition clearly in the title and description so buyers know exactly what they’re getting.
- Ship items quickly and always use tracking.
- Respond to buyer messages promptly. Fast responses can make the difference between a sale and no sale.
- Share listings in parent Facebook groups or local resale groups where families are looking for affordable kids clothing.
- Consider seasonal timing. Listings for winter coats, school uniforms, and summer outfits tend to sell best just before those seasons begin.
How Vendoo Can Help
Selling kids clothes across multiple platforms can become time-consuming if you’re creating separate listings for every marketplace. Vendoo helps simplify that process!
With Vendoo, you can create a single listing and crosslist it to multiple platforms such as eBay, Mercari, Poshmark, Depop, Etsy, and Facebook Marketplace. Instead of manually inputting the same title, description, and photos several times, you enter the information once and publish it across several marketplaces.
Another helpful feature is automatic delisting. When an item sells on one platform, Vendoo can remove the listing from the others. This reduces the risk of accidentally selling the same item twice and having to cancel an order.
Vendoo also helps sellers stay organized with inventory management tools. If you update the price of a bundle or adjust the quantity of items, those changes can be applied across multiple listings without logging into each platform.
For clothing sellers, photos are important. Vendoo includes bulk photo editing tools and templates that help keep listing photos clean and consistent.
Ultimately, a crosslisting workflow helps you reach more buyers without extra work. For example, you might create one listing for a “Girls 4T Summer Bundle” in Vendoo and send it to multiple marketplaces like eBay, Mercari, Poshmark, and Facebook Marketplace at the same time. Instead of recreating the same listing on six different apps, you can manage everything from one place.
Final Thoughts
The best place to sell kids clothes online depends on what you’re selling and how much effort you want to put into it. Consignment options like ThredUp can be convenient for bulk items, while marketplaces such as Poshmark, Mercari, and eBay give you more control.
Many sellers get the best results by combining a few platforms. Listing bundles, pricing competitively, and testing different marketplaces can help you figure out what works best for you.
