Selling vintage clothing finds: grade, measure flat, disclose everything

Reselling · 7 min read

Vintage clothing is the flip category where the listing does the most work, because the buyer cannot touch the garment and often cannot trust its size tag. A modern medium and a 1970s medium are different objects, so experienced vintage buyers shop by the tape measure, not the label — and they forgive almost any flaw except a surprise. The seller guides for this category converge on one workflow: inspect in good light, grade on a consistent scale, measure everything flat, photograph every flaw as its own picture with its own line in the description, and price from completed sales. This guide assembles that workflow for auction and estate finds, including the two judgement calls the short guides skip: where a flaw sits changes its grade, and when a garment should not be listed at all.

A note on money: general information about reselling only — not financial advice, and no garment is guaranteed to sell at any price.

Inspect and grade: one scale, applied the same way every time

Size.ly's complete guide to selling vintage clothing online sets the inspection standard: inspect the garment in natural light and document any flaws — pinholes, underarm stains, fading, loose hems, broken zippers, and moth damage should all be photographed and mentioned — because disclosing small flaws honestly usually will not deter a sale, while hiding them leads to returns and bad reviews. Its grading scale is the one used throughout this guide: Deadstock / NWT — never worn, original tags intact; Excellent — light wear, no significant flaws; Good — visible wear consistent with age, minor flaws disclosed; Fair / for repair or rework — notable damage, priced to reflect it. The same guide adds the authentication caution: for designer pieces, check that the label matches known examples — font, tag construction, country of origin, and the RN number — before claiming a brand, because misattributing a brand is a fast path to a refund demand.

Where the flaw sits changes the grade

GradeThread's stain-grading guide adds the refinement that separates a working grade from a guess: two flaws of the same size can land in different tiers, because prominence, contrast, fibre damage, and count all move the call. A one-centimetre spot on a graphic tee's print counts far heavier than the same spot inside a jacket's sleeve lining; a dark spot on white costs more grade than a tonal mark on navy; a stain area that feels stiff, thin, or brittle is no longer cosmetic — it is fabric damage; and many small spots read worse than one. Its mapping is a useful working table: a faint shadow visible only at an angle in a hidden area leaves a garment Very Good; a light visible set-in mark in a minor area makes it Good; a clear stain on the chest, front, or sleeve makes it Fair; and large or multiple stains, or rust or mildew weakening the fibre, make it Poor. A visible yellow underarm mark rules out Excellent on its own. And when two tiers both seem plausible, GradeThread's rule is the one to keep: grade down. A buyer who receives a Good that looked like Fair rarely complains; the reverse is a return.

Measure flat, and publish every number

Underpriced's vintage flipping guide states the reason in one line: vintage sizing rarely matches modern sizing, so buyers trust the tape more than the tag — measure flat, in inches, and put the numbers in every listing. Its measurement sets are the standard ones, and they differ by garment type, which is the detail sellers most often flatten into a single "size" line:

The same guide's flaw rule pairs with the tape: give every meaningful flaw its own photo and its own line — stains even when faint, pinholes, seam pulls, repairs, fading that changes the colour, missing or replaced buttons, and thin spots at knees, elbows, collar, and underarms — because buyers forgive wear much more easily than surprises. If you date the piece, say how: the guide's example is "1970s, based on the union label and care tag," which is an evidence claim a buyer can check, rather than a vibe.

Price from completed sales, and leave room for the offer

Underpriced's pricing method is the standard evidence rule used across this site: check vintage-clothing sold comps on eBay before setting a price, because recent completed-sale evidence is the most accurate market data. The factors it says move that evidence are brand recognition and era desirability, condition relative to the alternatives actually available, size availability (common sizes sell faster; genuinely rare sizes can command premiums), seasonal timing (its examples: leather jackets sell better in fall, Hawaiian shirts in spring), and platform norms — different marketplaces expect different pricing for the same garment. Its working tactic is to start 15–20% above your target to leave room for offers, then track the sell-through rate and adjust. On the buying runs behind this site, that adjustment step is where the money is protected: the figure watched most closely is how much sits unsold, and a rising pile is the cue to promote the older listings, re-check their photos, and cut prices before the rack — and the capital in it — stops moving.

When not to list it

1. Fibre failure: a garment whose fabric tears or powders under a gentle stretch has nothing to grade — it will not survive normal wear, and no discount fixes that honestly.
2. An unverifiable brand claim: if the label does not match known examples, list the garment as what you can prove — style, era evidence, measurements — or do not list it as the brand at all.
3. A flaw you cannot photograph clearly: if the damage cannot be shown, it cannot be disclosed, and an undisclosable flaw is a future return. Keep the piece out of the listing until it can be shown.

What success looks like: the buyer receives a garment that is, measurement for measurement and flaw for flaw, exactly the one in the listing — and the sell-through rate on the rack stays high enough that unsold stock is a number you review, not a pile you avoid looking at.

FAQ

Should I wash or repair a garment before listing? Cleaning that you disclose is safe; repairs should be listed as repairs, in their own line, per the flaw rule above. Never let a repair silently upgrade a grade — the grade describes the garment as the buyer receives it.

The tag says medium. Why publish measurements at all? Because the tag describes the sizing system of its decade, not the buyer's. Underpriced's whole measurement section exists because vintage buyers have learned this; a listing without measurements asks them to gamble, and most will not.

Is a flawed garment worth listing at all? Often, yes — at Fair, priced to reflect it, with the flaw photographed. The guides are consistent that disclosed flaws rarely kill a sale. What kills sales, and seller accounts, is the flaw the buyer discovers alone.
