The Best Places to Buy Used Kids Clothes Online (And What to Avoid)

Let’s be real: buying clothes for kids feels like trying to hit a moving target. They grow fast. They stain everything. And those cute $28 pants? Worn once. Maybe.

That’s why I started buying used kids clothes—and now it’s one of the easiest decisions I make as a mom. It’s budget-friendly, planet-friendly, and honestly? It just makes sense.

But not all secondhand sites are created equal. Some are gold mines. Some… not so much.

Here’s my honest guide to the best places to buy used kids clothes online—and what I skip.

The Little Loop (Community Swapping, Simplified)

Okay, I’m a little biased here—but I built The Little Loop because I couldn’t find a secondhand option that was truly built for parents.

It’s not a store—it’s a swap platform. You send a box of your child’s outgrown clothes and get matched with a family who needs that exact size and gender. Then you receive a box back when you’re ready.

•  No photographing or listing
•  No awkward porch pickups
•  No endless scrolling

Just out with the old, in with the gently used.

ThredUp (Best for Brand-Name Finds)

ThredUp has a massive selection of secondhand kids’ clothes—everything from Carter’s and Cat & Jack to Boden, Tea, and Zara.

Pros:

•  
• Great filtering by size, brand, and condition
•  
• Bundles + curated packs available

Cons:

•  
• Some items can still be pricey
•

Kidizen (Parent-Powered & App-Friendly)

Kidizen is a resale platform made just for kids’ items. It has a great app, and most sellers are parents just like you.

Pros:

•  
• Easy to shop by age, size, or brand
•  
• Lots of boutique and organic brands

Cons:

•  
• Prices can be closer to retail
•  
• Shipping is per seller, not bundled

eBay (Great for Bulk Lots)

eBay is still one of the best spots for scoring secondhand kids clothes in bulk. Search by brand and size to find bundles of 10–20 pieces at once.

Pros:

•  
• Huge selection
•  
• Great for basics (onesies, pajamas, leggings)

Cons:

•  
• No size consistency
•  
• Photos and quality can vary widely

What I Skip (Most of the Time)

•  
• Generic fast-fashion resellers (often overstocks, not true secondhand)
•  
• Pricey consignment sites with minimal inventory
•  
• Mystery boxes that don’t let you preview brands, styles, or condition

Final Thought

Buying used kids clothes isn’t just a thrifty parenting hack—it’s a smart, sustainable shift that actually makes your life easier.

You’ll spend less. You’ll stress less. You’ll have fewer clothes with more value.

And when you’re ready to pass them on? You know what to do.
