Sell Kids' Clothes: 8 Smart Ways to Make Money (2026)
Below you'll find detailed information about each option, including what makes them unique and their key benefits.
1. Shopify
Shopify lets you build a dedicated online store to sell kids' clothes under your own brand, with no coding required. Plans start at $19–25/month with a 3-day free trial, making it affordable for parents or boutique owners looking to turn a children's clothing side hustle into a real business. You control pricing, branding, and inventory without paying per-sale fees to a third party.
Key features:
- Built-in payment processing, shipping tools, and inventory management
- Pre-built themes work well for clothing boutiques
- Best for: Entrepreneurs wanting a branded storefront for children's apparel
Facebook Marketplace is one of the fastest ways to offload secondhand kids' clothes locally — list items in minutes and reach buyers already browsing in your area. There are no selling fees for local cash transactions, which makes it ideal for parents clearing out outgrown baby and toddler clothing. Shipping options are also available for wider reach.
Notable perks:
- Free to list; no fees on local pickup sales
- Large built-in audience with neighborhood-level targeting
- Best for: Parents selling used children's clothing quickly without fees
3. Poshmark
Poshmark has a strong market for secondhand children's clothing, with buyers actively searching for name-brand kids' items like Gap, Carter's, and Old Navy at discount prices. Listing is free, and Poshmark handles payment processing — they take a flat $2.95 on sales under $15 and 20% on sales above. Shipping is simplified with a prepaid label sent to you after each sale.
What you get:
- Built-in buyer base specifically seeking resale kids' apparel
- Prepaid shipping labels on every order
- Best for: Resellers with multiple pieces of gently used children's clothing
4. Bounce Mkt
Bounce Mkt is a resale marketplace built specifically for buying and selling secondhand children's items, making it a natural fit for parents looking to offload outgrown kids' clothing. The platform connects sellers directly with buyers who are already searching for gently used children's apparel, reducing the time it takes to move inventory.
Key features:
- Category-focused on children's items, so listings reach targeted buyers
- Seller-friendly listing process designed for individual parents, not just retailers
- Local and shipped selling options available
5. Sellas
Sellas is a peer-to-peer selling app that lets parents list and sell children's clothing quickly through a mobile-first interface. It's particularly useful for moving small lots of outgrown baby or toddler clothes without the complexity of managing a full storefront or paying steep commission fees found on larger platforms.
Notable perks:
- Mobile app makes photographing and listing clothes fast
- Direct buyer-seller messaging to negotiate or bundle items
- Low barrier to entry for casual or first-time sellers
Shop Tomorrows focuses on sustainable children's fashion resale, attracting eco-conscious buyers specifically looking for quality secondhand kids' garments. If you're selling higher-end or brand-name children's clothing — think Hanna Andersson, Mini Boden, or Primary — this audience is more likely to pay fair prices rather than bargain-hunt.
What you get:
- Niche audience of sustainability-minded parents willing to pay more for quality brands
- Curated marketplace feel that elevates perceived item value
7. JBF Sale
Just Between Friends (JBF) is a seasonal consignment sale franchise where parents can sell outgrown children's clothing twice a year — typically spring and fall. You tag your own items, drop them off at a local event, and collect a check after the sale ends. Sellers typically keep 60–70% of the selling price, with the option to earn more by volunteering at the event.
Key details:
- Sellers set their own prices and keep 60–70% of proceeds
- Items not sold can be donated or picked up after the event
- Events run in hundreds of cities across the U.S.
Once Upon a Child is a brick-and-mortar resale chain that buys used kids' clothing directly from you — no waiting for items to sell. Bring your gently used children's clothes to any location, and staff will assess and make an on-the-spot cash or store credit offer. It's one of the fastest ways to convert a bag of outgrown clothes into immediate payment without listing fees or shipping.
What to expect:
- Instant cash offers — no waiting period
- Accepts clothing, shoes, and gear for newborns through teens
- Over 350 store locations across North America
9. Kid to Kid
Kid to Kid operates similarly to Once Upon a Child as a physical resale store that purchases secondhand children's clothing outright. Bring in a bin of kids' clothes and walk out with cash or store credit on the same visit. If you prefer exploring alternative selling platforms beyond in-person stores, Kid to Kid still makes a reliable fallback for quick, no-hassle sales with no listing or commission fees.
Notable perks:
- Same-day cash or store credit for accepted items
- Stores located primarily in the U.S. and internationally
Final Words
Your best bet depends on whether you want quick local sales or maximum reach — platforms like selling on Facebook Marketplace work great for fast pickups, while resale apps can earn you more over time.
