Secondhand Fit Is a Different Game
Buying secondhand online — on resale apps, vintage shops, or marketplaces — is booming, but it removes every safety net. There's no fitting room, often no returns, and the size label may be decades old and meaningless. Getting fit right takes a different approach than shopping new. Here's how seasoned thrifters do it.
Ignore the Label, Trust the Measurements
A vintage "Medium" can be smaller than a modern Small, because sizing has drifted over decades — the size inflation we explain in What Is Vanity Sizing. So the label on a secondhand item is the least reliable signal. What matters is the seller's measurements.
- Know your own body measurements and your favorite garments' flat measurements.
- Compare those to the listing's stated measurements.
- If measurements aren't listed, ask — a good seller will provide them.
What to Ask the Seller
- Flat measurements for the key points (chest/waist/hip/length, etc.).
- Fabric and stretch — "any give?" changes everything.
- Condition notes that affect fit — stretched-out areas, shrinkage, alterations.
- Modeled or laid-flat photos for a sense of drape.
Judging Fit From Photos
When you can't try on, photos are your fitting room:
- Laid-flat shots let you eyeball proportions.
- On-body shots (with the seller's size noted) show drape and length.
- Close-ups reveal fabric and any wear that affects fit.
This is the predict-before-you-buy skill from How to Tell If Clothes Will Fit Before You Buy, applied to resale.
Account for Vintage Quirks
Older garments were cut for different proportions and standards. Expect higher rises, different shoulder slopes, and smaller-than-modern sizing — more on this in Why Vintage Clothes Run Smaller. Build in a little caution, and factor in that alterations are often part of vintage shopping.
Where YourSizer Fits
Secondhand shopping rewards the same skill YourSizer automates: translating measurements into fit. YourSizer does that translation for brands and shoppers buying new, turning a body and a garment's measurements into a confident size. See it for brands, shoppers, or pricing.

Frequently Asked Questions
How do I buy secondhand clothes that fit?
Ignore the (often outdated) size label and rely on measurements. Know your body and favorite garments' flat measurements, compare them to the seller's stated measurements, and ask for them if they're missing. Judge drape from laid-flat and on-body photos.
Why do secondhand and vintage sizes run small?
Clothing sizes have drifted larger over decades through size inflation, so an older garment labeled "Medium" can be smaller than a modern Small. The label reflects the standards of its era, which is why measurements matter more than the tag.
What should I ask a secondhand seller before buying?
Ask for flat measurements of the key fit points, the fabric and whether it has stretch, any condition issues that affect fit (stretching, shrinkage, alterations), and modeled or laid-flat photos with the seller's own size for reference.
