Review Methodology
TrainingBras.com separates sourced product facts, normalized database fields, editorial interpretation and future hands-on observations so readers can tell what kind of evidence supports each statement.
1. Identify the exact product
We start with the current manufacturer product name and source URL. Similar product-family names are not assumed to be interchangeable. If a style has its own chart or construction exception, that exception belongs to the product record.
2. Verify manufacturer facts
Sizes, materials, closure, strap configuration, padding/lining, care instructions and manufacturer-described use cases are recorded only when a current source supports them. Unknown fields remain unknown.
3. Record provenance
The database distinguishes manufacturer-direct information from manufacturer data reproduced by a retailer and from any future TrainingBras.com observation. This matters because two sources can contain the same field while having different verification strength.
4. Normalize without changing meaning
Product records are mapped into common fields so users can compare like with like. Normalization should make data easier to compare without creating facts the source never stated. For example, a marketing phrase such as “soft feel” is not converted into a laboratory fabric-performance claim.
5. Evaluate decision attributes
For editorial comparisons, we focus on practical attributes such as use case, padding, closure, straps, back style, material wording, construction, support context and sizing model. The Finder and comparison engine use the same normalized product records.
6. Keep sizing separate from product similarity
Two products can be similar in construction while using different sizing systems. Product similarity never proves size interchangeability. Cross-brand sizing begins with current measurements and the applicable manufacturer chart.
7. Apply the 5-Point Fit Check
Where fit guidance is relevant, we use the TrainingBras.com framework: band, straps, front, movement and overall comfort. This is a practical fit checklist, not a medical assessment or a guarantee that a product will fit every wearer.
What we will never claim
- that we personally tested a product when we did not;
- that a manufacturer claim is an independent scientific finding;
- that one size chart is universally accurate;
- that an affiliate relationship makes a product a better match;
- that a database similarity score is a quality or comfort score.
Future Product Lab
If hands-on testing begins, the protocol will be published before its findings are represented as independent observations. Possible measurements include garment dimensions, strap width, padding configuration, material composition, wash behavior and shrinkage. Sample size, test conditions and limitations will be disclosed.
Re-verification
Manufacturer pages change. When a material sizing or product change is discovered, the record should be rechecked, its verification date updated and dependent comparison logic reviewed. See the Corrections Policy and Data Methodology.
