About UBBRA

UBBRA is an independent bra-fit decision tool built for the moment after a bra or calculator result fails.

What UBBRA does

It separates band tension, cup volume, cup shape, wire geometry, center fit, strap behavior, asymmetry, and garment wear. The goal is to recommend the next useful comparison—not to claim that one formula can identify a universally correct size.

What UBBRA does not do

UBBRA does not diagnose medical conditions, guarantee fit across brands, or claim that letter sizes are standardized worldwide. It currently supports UK, US, and EU sizing as practical reference systems and uses relative steps when an exact label would be misleading.

Why the starting point is a real bra

Measurements can suggest a starting point, but a bra you have actually worn gives additional evidence: whether the band moves, where the wire sits, where a cup gaps or spills, and whether the construction is too tall, wide, narrow, or shallow.

Independence

At launch, Fit Rescue does not depend on affiliate rankings, paid placements, or a commercial sizing API. If monetization or commercial relationships are added later, they should be disclosed where relevant and should not silently rewrite the fitting logic.
