The Resale Boom Is Real: How Secondhand Platforms Revolutionized Shopping (and How to Cash In)

Ten years ago, buying secondhand meant digging through crowded thrift-store racks and hoping you got lucky. Today, resale is a $256 billion global industry — and it's still accelerating.

According to ThredUp's 2026 Resale Report, based on research by analytics firm GlobalData, the global secondhand apparel market grew from $141 billion in 2021 to an estimated $256 billion in 2025. That's an 82% jump in four years. ThredUp projects another 12.5% of growth this year, pushing the market to $288 billion — and $393 billion by 2030, roughly 10% of everything the world spends on clothes.

In the U.S., resale grew 19% last year — its strongest year since 2021 and nearly four times faster than traditional retail clothing, per Chain Store Age's breakdown of the report. 59% of American consumers bought secondhand apparel in 2025, up seven points in three years.

This isn't a trend. It's a takeover. 🖤

How resale platforms changed the game

1. They made secondhand searchable. When eBay launched in 1995, listing a used item was a project — digital camera, SD card, a prayer for your dial-up connection. Now you can find exactly the piece you want, in your size, in seconds. And it's getting easier: Treet's CEO told Retail Brew that AI now generates entire listings from a single photo. At BudMila's Closet, we work the same principle every day: good data sells. We research every piece against exact-model sold prices before it lists — so buyers know the price is real, and sellers know they're getting real value.

2. They made it trustworthy. Authentication and buyer protection killed the old fear of "is this actually real?" That's the foundation BudMila's Closet is built on — your everyday marketplace, and your trusted partner whether you're buying a designer piece or handing us your closet to sell.

3. They brought in a generation. 62% of Gen Z shopped secondhand in 2025, and Gen Z plus millennials are expected to drive over 70% of resale growth through 2030. ThredUp's CEO put it bluntly: "Resale is no longer just growing, it's taking share." 58% of retailers now agree that having no resale presence is a permanent structural disadvantage.

4. They turned every closet into a store. Anyone with clothes they don't wear is sitting on inventory. Right now the industry's bottleneck isn't demand — it's supply. That means sellers have more leverage than ever.

How to take advantage of the boom

If you're buying: this is the golden age. Designer and brand-name pieces at a fraction of retail, one-of-one finds you can't get anywhere else, and a smaller footprint than buying new. BudMila's Closet adds new listings every single day — Gucci, Versace, Tom Ford, Nike, and hundreds more — all researched, all inspected, all ready to wear.

If you're selling: don't let your closet sit on dead money. Consign with us — we photograph, research, price, and list your pieces across the platforms where buyers actually are, and you get paid when they sell. It's the easiest way to turn clothes you don't wear into cash you can use.

The bottom line

Resale platforms didn't just change how we shop — they changed what shopping means. The smartest shoppers aren't asking "new or used?" anymore. They're asking "where's the best piece at the best price?" More and more, the answer is secondhand.
