You probably have a section of your closet that’s basically a storage unit: jeans that don’t fit, work dresses from three jobs ago, kid clothes they outgrew overnight. Together they add up to real cash that can cover boring, necessary stuff like groceries, co-pays, and one more chunk off a credit card.
The trick is matching the right items to the right site so you’re not wasting time on lowball offers or confusing fees.

Poshmark
Poshmark is basically a giant online clothing swap with money involved. It’s best for mall and mid-range brands (think Old Navy through Madewell), plus athletic wear and trendy shoes. You snap a few photos, add size and brand details, set your price, and Poshmark sends you a prepaid shipping label when something sells. They keep a flat cut of each sale, 20% on items over $15, and a flat fee on smaller sales, and you keep the rest.
Poshmark works well if you’re willing to treat this like a casual side hustle. Sharing your listings inside the app, joining “Posh parties,” and cross-posting your closet on social all help items move faster. Grouping similar things into bundles (like three pairs of leggings in one listing) can justify a higher price and reduce how often you’re packing orders. If you have a closet full of recognizable brands in good condition, this is a straightforward way to turn them into cash without learning a complicated system.
thredUP
If you want the money but not the effort, thredUP is the “please just take the whole pile” option. You order a Clean Out Kit or print a prepaid label, stuff a big box or bag with clothes, and ship it in. thredUP handles photography, listings, pricing, and shipping to buyers. In exchange, they keep a large part of the sale price; your payout depends on brand, condition, and how fast it sells.
This makes sense for people with more time pressure than money pressure, busy parents, full-time workers, or anyone staring at ten trash bags of clothes. You won’t get top dollar for each item, but you also won’t be answering questions about inseams at 9 p.m. Focus on sending in in-season, name-brand pieces in excellent condition; fast fashion basics and worn items often get rejected or pay next to nothing. Check thredUP’s payout estimator before you ship so you’re not surprised by the numbers, and treat whatever comes in as “found money” for stuff that was just sitting there.
Depop
Depop is part resale app, part social media. It’s especially strong for Y2K, streetwear, vintage, and anything that photographs well styled on a person. Listings live inside a feed-style profile, and buyers can like, message, and follow you. Depop charges a selling fee plus payment processing when an item sells, so price with that in mind.
Depop rewards a certain “look.” Think mirror selfies, clean backgrounds, and outfits instead of flat-lay piles. If you’re already taking selfies or outfit pics, you’re halfway there. This is a good fit if you have a strong sense of style and enjoy curating a little “shop”, not just dumping random clothes. Niche brands, band tees, and unique thrift finds can do really well here. To make it worth your time, batch list: photograph 10–20 items at once, write simple but keyword-rich descriptions (“black Nike tech fleece joggers men’s medium”), and be responsive to offers. It’s less ideal for basic work trousers and more for the fun stuff.
eBay
eBay is still the big, messy, powerful option if you want maximum reach. You can sell everything from Target basics to rare designer pieces, plus shoes, bags, and accessories. You choose auction or “Buy It Now,” set shipping, and eBay takes a cut, in clothing categories, typical fees land in the low-to-mid teens as a percentage of the total sale once you factor in their final value fee and fixed per-order charge.
Use eBay when you’ve got something that people might actually search for: a sold-out collaboration, plus-size styles with limited options elsewhere, or specific workwear brands. Look up completed listings before you price so you know what things actually sold for, not just what other sellers are dreaming about. Auctions can be great for truly in-demand pieces; for everything else, fixed price with “Best Offer” is safer. Shipping is where people lose money, so weigh items in the package and use eBay’s shipping calculator instead of guessing. Done right, eBay can pull in more per item than many apps, especially for higher-value pieces.
Mercari
Mercari is a simple, no-frills marketplace that’s big on secondhand fashion, shoes, and everyday stuff. You snap photos, write a short description, set your price, and choose whether you or the buyer pays shipping. When it sells, Mercari currently charges a 10% selling fee on the item price and buyer-paid shipping, and a separate buyer-side protection fee, still usually less cluttered than eBay’s fee maze.
Mercari works well if you want straightforward math and don’t care about “social” features. Everyday brands, kids’ clothes, and practical shoes move here if they’re priced right and photographed clearly. A lot of buyers filter by condition and free shipping, so build the cost of shipping into your price and label it “free” if you can. To protect your profit, avoid listing super-low-priced items one by one; either bundle or wait until you have a small pile to justify the time and fees. Respond quickly to questions and offers, serious buyers often move on fast.
Vinted
Vinted just expanded into the U.S. after dominating secondhand fashion in Europe, and it’s built around one big promise: no selling fees. Buyers pay a small “Buyer Protection” fee on top of your price, plus shipping, and you get the full list price when your item sells.
That alone makes Vinted a smart pick if you’re tired of watching 15–20% vanish in fees on other platforms. It’s good for mid-range brands, kids’ clothing, sneakers, and athleisure, anything clean, on-trend, and fairly priced. Because buyers pay their own fee, they’re extra sensitive to inflated prices; checking similar sold listings will help you land in the “feels fair” zone. Shipping is mostly handled through prepaid labels and drop-off points, which cuts down on post office drama. To avoid headaches, be extra honest about flaws and take clear photos; like every peer-to-peer platform, disputes about condition are a pain you don’t need.
Facebook Marketplace
Facebook Marketplace is the “cash in hand by tonight” option. It shines for bulky items like winter coats, boots, job interview outfits, and big kid clothing lots that are annoying to ship. You list the item, set a price, and decide whether you’re doing local pickup, shipping, or both. Facebook also supports shipping with checkout and built-in payments, charging a small selling fee on shipped orders.
Marketplace is best for people who want speed and are comfortable meeting buyers in person. Grouping kids’ clothes into size-labeled bundles (“25 pieces, boys 6–7, school and play clothes”) lets you move volume fast and saves parents a ton of time, which justifies your price. Safety matters here: meet in public, daylight-only, and stick to cash or through-the-app payments. If you have a lot to sell, join local buy/sell groups as well, they often have more serious shoppers than the general Marketplace feed.
Vestiaire Collective
If you have actual designer piece, not “inspired by,” but the real thing, Vestiaire Collective is built for that. The platform focuses on pre-loved luxury fashion and accessories, with expert authentication and a global audience. Sellers list items, set prices, and ship to Vestiaire or directly to buyers depending on the item. Fees vary, but they’ve been pushing lower commissions and even zero-selling-fee promos on certain brands and price ranges.
Vestiaire makes sense if you own designer bags, coats, or clothing that you originally paid real money for. Their curation and authentication can justify higher resale prices than general sites, buyers feel safer spending big. Your job is to be meticulous: clear shots of labels, serial numbers, receipts if you have them, and honest condition notes. Because this is an international platform, be prepared for longer shipping windows and picky buyers. On the flip side, a single sold designer piece here can wipe out what you’d make from a whole pile of mall-brand tops on other apps.
The RealReal
The RealReal is another heavy hitter for high-end items. Instead of you handling listings, they operate as a managed consignment service: you ship or drop off your luxury clothes, handbags, jewelry, and shoes, they authenticate and list them, and you get paid once they sell. Their own materials say many items sell within about 30 days, which is appealing if you’re trying to free up cash quickly.
The RealReal is best when you have pieces from brands they love, think designer labels, not fast fashion, and you don’t want to deal with individual buyers. Commission rates vary by category and price, but you’re trading some potential profit for pure convenience and the trust their brand already has with high-end shoppers. Before you send anything, check their accepted brands list and estimated payouts so you don’t box up items they’ll reject. For big-ticket pieces cluttering your closet, this can be the least stressful way to turn them into a meaningful chunk of cash.
Grailed
Grailed started as a menswear resale platform but now includes women’s pieces and unisex styles, with a strong focus on designer, streetwear, and high-quality vintage. It’s where people hunt for specific brands and rare pieces, not random fast-fashion jeans. You list items with detailed brand and condition info; buyers can make offers or buy outright.
Use Grailed when you’ve got items that fashion nerds care about: heritage denim, archival pieces, limited collabs, or well-made basics from respected labels. Buyers tend to be picky but willing to pay if you provide good photos and measurements. Unlike more casual apps, there’s an expectation that you know what you’re selling; take a minute to research model names and fabric content. Fees are similar to other fashion marketplaces, so the real advantage is the audience, these are people actively searching for the brands you might otherwise undersell on a general site. One or two well-priced sales here can out-earn a whole stack of “meh” items listed elsewhere.
StockX
If your “old clothes” include serious sneakers or hype streetwear, StockX (https://stockx.com) treats them like a stock market. You don’t write flowery descriptions; you pick the exact item from their catalog, set an “ask” price, and wait for a buyer’s “bid” to match. When your shoes or streetwear sell, you ship them to StockX for verification before they go to the buyer. Every item is authenticated, which is a huge draw for buyers nervous about fakes.(StockX)
StockX works best for recognizable releases: Jordans, Dunks, Yeezys, collab sneakers, and some branded apparel or accessories. Before you list, check recent sale prices so you’re not underpricing something that quietly skyrocketed. Fees are higher than selling to a friend, but you’re paying for instant access to a global pool of sneakerheads who are used to market-level pricing. Condition rules are strict; most items must be new or near-new. If you’ve been sitting on deadstock sneakers or hype hoodies “for later,” this is a structured way to cash them out.
GOAT
GOAT is another giant in sneaker resale, also branching into apparel and accessories. Like StockX, it authenticates items, but it offers both new and used listings and lets some sellers ship directly to buyers while others ship to GOAT first for verification. That mix can make it easier to move gently worn sneakers and streetwear.
GOAT is a good choice if you have sneakers with a little life on the soles but still in solid condition, or branded streetwear from labels that have a following. Upload clear photos, including soles and tags, and be honest about wear, buyers are used to seeing graded condition here. Because the platform focuses so heavily on authenticity, you may get higher offers than you’d see on more general apps for the same shoes. If you’re trying to decide between StockX and GOAT, it sometimes makes sense to cross-check prices and go where your specific item is selling faster and higher.
Etsy
Etsy isn’t just for handmade crafts. It’s also a major marketplace for true vintage clothing, items at least 20 years old, and upcycled or reworked pieces. If you’ve been thrifting for years or inherited older clothing that’s stylish again, Etsy gives you a way to reach people actively searching for “90s leather jacket” or “80s prom dress.”
Etsy makes the most sense if you want to build a small, curated shop rather than dump everything at once. You’ll pay listing fees plus a cut of each sale and payment processing, so this isn’t ideal for $8 fast-fashion tops. Focus on unique, high-quality vintage, plus altered or upcycled pieces where your labor adds value. Good photography and detailed keywords (“70s prairie dress floral medium,” not just “cute dress”) are crucial. The upside is that buyers come here ready to pay more for special pieces. If you treat it like a real micro-business, consistent branding, clear policies, thoughtful packaging, Etsy can turn your eye for vintage into steady extra income.
Whatnot
Whatnot is a live shopping marketplace, imagine eBay plus TikTok. Sellers run live shows where they hold up items, chat with viewers, and auction pieces in real time. Clothing and fashion are big categories, and many sellers run themed shows like “all vintage tees” or “plus-size mystery bundles.” Standard seller fees include a commission on the sale price plus payment processing.
Whatnot is best for outgoing people who don’t mind being on camera and talking for an hour. If that sounds fun instead of terrifying, it can be a fast way to move a lot of clothing in one session and build regular customers. You don’t need fancy equipment, a phone, decent lighting, and a table or rack is enough to start. The key is energy and honesty: show flaws, answer questions, and keep the pace moving so buyers stay engaged. If you’re already sitting on bins of inventory from other platforms, a few live shows can clear space and generate cash without writing 50 separate listings.
