Reselling News: eBay's Size Dropdown Has No Room for a 33 Waist, and Vintage Demand Is Up 432 Percent

Clothing is where most of us make our money, and this week produced one story about the plumbing of selling it and one about the demand behind it. Take them in that order.

eBay standardized apparel sizes, and some real sizes did not make the list

eBay announced size standardization for Apparel and Footwear back in May, started normalizing obvious values in June, and in August began blocking listings that carry a size the system does not recognize. Value Added Resource covered the rollout when the deadline was still ahead: blanks, "See description," and combined entries like "S/M/L" stop passing, and listings that fail can be held or blocked on creation or revision.

The part nobody planned for is now showing up. EcommerceBytes reported on September 10 that sellers are getting notices their current sizes are no longer valid, then opening the dropdown and finding no option that matches the garment in their hands. The two examples going around are a men's 33 waist in pants and a 39R blazer. Neither is an odd size. A 33 waist sits on the rack at every department store in the country. Sellers also said eBay did not hand them a list of which of their listings were the problem, so finding them is manual.

The workaround being passed around is to pick the closest supported value in the item specific, then state the true size in the title and the description, which is also roughly what eBay's own guidance says to do when there is no exact match. It works, and it costs you something. Item specifics are what eBay's search filters read, so a 33 listed as a 32 shows up for the wrong shopper and misses the right one, and it raises your odds of a not-as-described return.

Two things to do this week. Pull up your active apparel listings and check the ones with in-between or odd sizes, because eBay is not going to point them out for you. And when you are sourcing, open the sell form on your phone before you buy something that sits between sizes. If the size you are holding is not in the dropdown, you now know in advance that the listing will fight you.

Vintage demand is not slowing down

The RealReal's 2026 resale report, published August 25, says demand for vintage on its platform is up 432 percent since 2020. Decade-specific saved searches rose 135 percent year over year, and searches for 2000s fashion jumped 93 percent. ThredUp's own report puts the global secondhand market at $393 billion by 2030, with US resale reaching $78.8 billion and growing about four times faster than retail overall.

The interesting part is why. Speaking on Marketplace on September 9, secondhand writer Karina Cohen described the shift as an attitude change rather than a spending change: shoppers are buying with future resale value in mind, and the growing appetite for items in as-is condition reads as both a taste for character and a way to spend less. She also made the point that a vintage piece does not carry the tariff cost that a new imported one does.

For you, that 135 percent number is the actionable one. Buyers are searching by era, not just by brand. If you are pricing a piece by brand alone, you are leaving the decade on the table. Learn to date a garment from the tag, the union label, the care instructions and the construction, then put the era in the title where the search can find it.

The takeaway

This week's two stories are the same story from both ends. eBay is tightening how a garment gets described, and buyers are getting more specific about what they want described. The sellers who win that trade are the ones who know their inventory well enough to describe it precisely, in the fields that search actually reads. Sharpening that eye, one garment at a time, is what The Income Lab is for.
