How it works · an explanation, not a sales pitch

§ I — Method Public · open vocabulary

How thrift.fit
decides what is
worth opening.

We start with garments you already trust, compare seller evidence against that baseline in inches, and keep the limits of every recommendation visible before you buy.

§ 01 — References

Your own closet is the sizing chart.

thrift.fit asks for garments that already fit because tag size is too noisy to trust. The diagrams below keep measurements concrete.

Reference examples Sample

Shirt

Brioni dress shirt

Chest: 21.0"
Shoulder: 17.7"
Sleeve: 25.4"

Illustrative sample photo of a Nanamica navy coat

Outerwear

Nanamica coat

Chest: 20.6"
Length: 29.3"
Sleeve: 24.9"

Trousers

Samuelsohn wool trousers

Waist: 16.4"
Rise: 12.1"
Inseam: 29.5"

§ 02 — Tag vs tape

Six mediums hide a three-inch spread.

The tag is treated as metadata. Tape measurements carry the fit decision because two items with the same label can land very differently.

Brand Sample Tag Chest Shoulder Spread

Vintage Brooks Medium 20.0" 17.1" Baseline

Drake's Medium 21.0" 17.7" +1.0" chest

Our Legacy Medium 22.2" 18.4" +2.2" chest

Uniqlo U Medium 22.8" 19.0" +2.8" chest

RRL Medium 21.5" 18.1" +1.5" chest

Engineered Garments Medium 23.0" 19.3" +3.0" chest

§ 03 — Scoring pipeline

Five stages from listing noise
to ranked shortlist.

Crawl

Collect listings from saved searches, active watchlist items, and imported candidate URLs.

Parse

Read seller measurements, listing text, images, category, brand, condition clues, and missing fields.

Compare

Line up each listing against your reference garments and category-specific tolerances.

Score

Fit gates the recommendation first. Brand ranks context after fit clears. Condition is assessed from the description.

Surface

Return a shortlist that explains measurement deltas, uncertainty, source, and next action.

§ 04 — Verdict language

One clear vocabulary for the product verdict.

Every surface uses the same recommendation contract: PASS clears the fit gate, MARGINAL needs judgment, and FAIL should be skipped.

Example verdicts Sample

PASS

Open first

The listing sits inside the fit gate and has enough supporting evidence to inspect confidently.

Fit score · 3.5 – 5.0

Chest +0.2"
Length +0.3"
Sleeve −0.1"

MARGINAL

Needs judgment

One fit dimension is close enough to consider, but the item should not rank like a clean match.

Fit score · 2.5 – 3.49

Chest +0.8"
Length −0.9"
Sleeve ok

FAIL

Skip

The fit miss is large enough that brand, condition, or price should not rescue the listing.

Fit score · < 2.5

Shoulder +1.3"
Sleeve −1.5"
Rise missing

§ 05 — Boundaries

Confidence comes from saying
what the system can and cannot know.

Can know

How seller measurements compare with garments that already fit you.
Whether a listing clears the hard fit gate before brand ranking.
Which measurements or images made the verdict weaker.
Where the item came from: saved search, watchlist, or discovery.

Cannot know

How the fabric feels in hand or whether alterations were done well.
Whether every seller measured from exactly the same points.
Future price drops, shipping surprises, or seller responsiveness.
Your personal styling preference on a deliberately oversized piece.

§ 06 — Saved searches

A repeatable hunt with seven days of history.

Saved searches make the workflow less dependent on memory. You can see whether today's shortlist is unusual or simply another normal pass through the market. The run below is a sample: illustrative figures, not live results.

Saved search Sample

Isaia blazers, size 40, US listings.

§ 07 — eBay watchlist

Your watchlist becomes a review queue, not a mystery pile.

The sync path is intentionally narrow: bring listings in, score them, show evidence, and leave final marketplace action to you.

Connecting eBay 4 steps · 4 min

01 Connect eBay from the hosted account.
02 Sync active watchlist listings into thrift.fit.
03 Evaluate new or changed items against your reference profile.
04 Review the ranked shortlist and open eBay only when you choose.

What we will do

Show active, removed, and historical watchlist context where available.
Keep fit evidence visible before recommending action.
Let you add back or remove items from the review workflow.

What we will not do

Buy anything for you.
Change protected eBay account settings.
Pretend missing measurements are certain.

§ 08 — Privacy

Three places where the boundary should stay obvious.

Measurements

Reference garment data exists to compare fit. It should be specific enough to help you buy, not more personal than necessary.

Marketplace access

eBay connection is used for watchlist and listing workflows. The page keeps the action boundary plain.

iii

Review history

Saved runs and verdicts make the shortlist auditable, while private shopping context stays inside your account.

§ 09 — Caveat

thrift.fit helps you decide what to inspect.
It does not make secondhand buying certain.

Measurements, images, and listing text can be incomplete or wrong. Treat the verdict as a fit-first signal, then use your judgment before bidding, offering, or buying.
