Sizing system
Yellowberry advises using each product page’s size guide and notes that clothing size alone may not predict bra fit. The company also advises sizing up when between sizes for some training-bra styles.
For any actual purchase, use the current product-specific chart when one is provided. A brand-level chart is a useful starting point, but construction differences can change how a particular style feels.
Construction and style attributes recorded
These are category-level attributes observed in the brand's current catalog or published guidance. They are not claims that every product from the brand has every listed feature.
How TrainingBras.com will use this record
- Identify the brand's sizing vocabulary before comparisons are made.
- Map measurement ranges only when the manufacturer publishes them.
- Record style-level exceptions separately instead of overwriting the brand default.
- Connect product attributes to our Types, Construction and Materials knowledge graphs.
- Require a current manufacturer source and verification date before data are used in a future translator.
