What we correct
- Factual errors. Wrong date, wrong attribution, wrong material, wrong label generation, wrong auction record. These are corrected on the page within 14 days of verification.
- Outdated price ranges. Auction comparables shift. If you have a recent (within 12 months) auction lot that meaningfully changes a range on an era or designer page, send it and we will update.
- Construction details we got wrong. If your expertise on a specific designer's interior construction contradicts what is written, we want to know. Send a photograph of the actual interior alongside the contradiction.
- Mis-attributed images. If a public-domain image is mis-credited or mis-dated, send the correct provenance and source.
How to submit a correction
Email hello@antiquecostume.com with:
- The specific page URL.
- The sentence or fact you are correcting (paste it exactly).
- The correction itself, with a source (museum holding, primary document, auction lot reference, your own documented expertise).
- Your name and how you would like to be credited if at all. We list contributors annually in the change log unless you decline.
How we handle a correction
We acknowledge every correction email within 7 days. We verify the correction against primary sources before publishing — usually within 14 days, occasionally longer if the source requires archive access. Corrections are made by rewriting the affected sentence on the page rather than annotating it; we treat the live page as the canonical version. The "Last reviewed" timestamp on the page updates when the correction ships.
For corrections that materially change a designer attribution, an authentication standard, or a market range, we add a footnote to the page change-log. Major changes get a one-line note in the site newsletter.
What we will not change
- Opinions and editorial framings. The pages take positions ("treating the Victorian era as one period is the first mistake", "Halston is overrated in the bag market, undervalued in the day-dress market"). Disagreement is welcome but is not a correction.
- Voice, tone, or style. We are not a neutral encyclopaedia and do not aim to be.
- Unsourced claims sent as corrections. We need a source we can verify.
