The Best Places to Buy Secondhand Kids' Clothes Online

If you're anything like us, you want your kiddos to look adorable without breaking the bank or contributing to fast fashion's environmental mess. Enter the world of online secondhand shopping—a treasure trove of stylish, affordable, and eco-friendly options.

No matter where you shop online, we always recommend following these tips to get the most out of your shopping experience:

• Be Specific: Use detailed search terms to find exactly what you're looking for.
• Be Mindful of Measurements: Kids’ sizes are all over the place. To avoid getting stuck with clothes that don’t fit consider buying known brands, checking measurements, sizing up, and/or ensuring that the store/seller allows returns when the size isn’t right.
• Review Seller Ratings: Look at seller reviews and ratings to ensure you’re buying from a reputable and trusted source.
• Inspect Photos: Clear, detailed photos can tell you a lot about the item's condition. If something isn’t clear in a photo, don’t be shy to ask for clarification or additional photos.

With those tips in mind, here’s a curated list of online spots where you can score preloved kids' clothes that are as kind to your wallet as they are to the planet.

1. Bounce Mkt

Okay, yes—we wrote this article, and yes, we’re putting ourselves at the top of the list. A little biased? Sure. But at Bounce Mkt, we’re all about making it super easy (and fun!) to shop gently used kids’ clothes that are actually cute, clean, and curated. We hand select every piece so you don’t have to dig through bins or scroll endlessly.

Whether you're shopping online from across the country or swinging by our Hoboken, NJ shop to browse in person, we’ve got you covered with high-quality secondhand kids’ clothing from kids’ fashion brands that you know and love.

2. ThredUp

ThredUp is an online consignment shop for both adult and kids’ clothing, with a huge selection of secondhand pieces you can filter by size, brand, and condition. Because there’s such a massive inventory, it can take a bit of time (and patience!) to scroll through everything, and quality can be hit or miss—so it’s worth reading descriptions carefully and giving photos a close look. That said, if you’re up for the hunt, there are definitely some hidden gems waiting to be found.

3. Poshmark

Poshmark is a favorite for scoring brand-name kids’ clothes at a fraction of retail prices. It’s a peer-to-peer platform, so you’re buying directly from other users, which can make for some great deals – though it can require a bit of back-and-forth with individual sellers on prices, and the shipping times and communication vary from seller to seller. But if you love the thrill of the deal, Poshmark can be a great way to score some real treasures.

4. Facebook Marketplace

Facebook Marketplace is a good option for finding secondhand kids' clothes, especially if you don’t mind a little bit of a hunt. You can find local deals and avoid pesky shipping fees, plus the prices can be quite low. The downside? It's a bit like rummaging through a yard sale online—there’s no guarantee of quality, it can feel a bit disorganized, and things can get a little chaotic in terms of communicating with individual sellers. But, if you’re willing to sift through what’s on offer, you might just score a sweet deal.

5. The RealReal

If you're on the hunt for high-end designer kids’ clothes at a fraction of the price, The RealReal is a great option! Known for its high-end consignment, this site offers curated collections of gently used luxury brands for children—think Burberry, Gucci, and Moncler. The catch? It's a bit of a splurge compared to typical secondhand shopping, but it offers some great luxe items if you’re looking to invest in timeless pieces for your little one’s wardrobe.

Happy shopping!
