Prior Art

What already exists, and the gaps that survived checking.

Compiled 4 September 2026. 39 rows surveyed across 8 categories.

Being wrong about novelty is cheap to find out now and expensive to discover after building. This survey was compiled on 4 September 2026 by headless web research across resale platforms, fibre-identification hardware, textile standards and registries, folding robotics, virtual try-on, colour-typing products and doorstep collection services.

Every row carries the tier of its source and a confidence value. A tier does not measure whether a claim is true, only how close the source sits to the thing it describes, and confidence records how firmly the research pass could stand behind it. Rows below 0.7 are marked, and the sources that could not be fetched at all are listed at the bottom.

Gaps that survived checking

Built strictly from gaps the research confirmed by fetching sources, not from the absence of a hit in a single search. These are the reasons the project is worth continuing, and they are the part most likely to go stale, so they are dated.

Load-bearing

No consumer resale platform has photo-to-measurement

ThredUp, Vinted, Depop, Vestiaire Collective and eBay all rely on manual seller-entered measurements. Depop and eBay generate titles and categories from a photo, and neither derives dimensions. This is a confirmed gap across all five platforms rather than an inference from one.

Load-bearing

Fibre identification is real, and has no consumer price point

Near-infrared fibre identification works and is deployed at industrial scale. It has no listing-integrated consumer path. The cheapest confirmed option, Matoha, starts at GBP 1,149 of hardware plus GBP 199 a month for API access, which is small-business rather than consumer pricing. Everything else is enterprise, quote-only, and physically installed in a sorting facility.

No documented automated defect detection

No platform describes autonomous defect grading in its own materials. The ThredUp 12-point inspection is explicitly human-driven in the source found, and the machine-learning layer at Vestiaire Collective flags anomalies rather than grading condition.

Load-bearing

No open, foundation-governed fabric quality score exists

Confirmed across all eight standards and registries checked. The nearest candidate in public law is the Digital Product Passport under the Ecodesign Regulation, and the textiles-specific act defining it had not been adopted at the time of this research. The nearest candidate in open source is circularity.ID, which is a real GPL-3.0 standard but company-led rather than foundation-governed. This is a genuine open window, and also not something to build against a confirmed specification yet.

Load-bearing

Automated folding remains unsolved outside a research lab

Confirmed by two well-capitalised commercial failures, FoldiMate in 2021 and Laundroid in 2019, and by the fact that the most advanced published work more than five years later is still an arXiv paper rather than a product.

Load-bearing

No commercially usable open-source virtual try-on

The three leading open models, IDM-VTON, OOTDiffusion and CatVTON, all carry CC BY-NC-SA 4.0 on both code and weights. They are self-hostable in the technical sense and non-commercial in the legal sense. For a project that accepts only permissive licences, that gap is decisive rather than inconvenient.

Load-bearing

Colour typing is crowded, and its evidence base is weak

The consumer app space is busy: Dressika, BeautySpark, My Color Seasons, BodyMuse, Fytted and Abody.ai all occupy it. A targeted search found no peer-reviewed controlled study validating the seasonal typing system against clothing-satisfaction outcomes. Whether that reads as a warning about a low-differentiation market or an opening for an evidence-based challenger is genuinely unresolved, and this survey does not resolve it.

Load-bearing

In Austria, the gap sits between giving it away and getting paid

Doorstep collection with a genuine revenue share exists here: Sellpy has been active since 2021, and Rebelle covers luxury. The three major Austrian charity channels, Humana, Carla and Volkshilfe, are donation-only with no payout to the donor. Österreichische Post pickup at EUR 3.48 is generic parcel logistics rather than resale-specific, and is a real usable building block.

On the half-remembered FOSDEM talk

The full FOSDEM 2026 schedule, roughly 1,079 events across more than 80 tracks, was searched directly against the primary schedule. There is no talk named open fabric or open textiles. The one genuine textile match is FreeSewing by Joost De Cock, an open-source parametric sewing-pattern generator with its code on Codeberg. It is a good project and it is not a garment-analysis or resale-listing tool, so it does not occupy this space. Recording that plainly is more useful than leaving a vague recollection standing.
