Informational service

UBBRA provides general garment-fit and shopping guidance. Its results are estimates for what to compare next, not a guarantee that a particular labeled size or style will fit.

Brand variation

Manufacturers use different patterns, grading rules, materials, wire shapes, and—in the US especially—cup-label progressions. Check the relevant brand’s size chart, product information, and return policy before purchasing.

Health boundary

UBBRA is not medical advice and is not intended to diagnose or treat pain, injury, skin problems, breast changes, or other health concerns.

External links

External links are provided for context or reference. UBBRA is not responsible for third-party content, availability, policies, products, or claims.

Availability and changes

The site may be corrected, expanded, or changed as fitting logic and content are reviewed. Material changes to privacy or data processing should be disclosed before the relevant feature is enabled.

Use of the site

Do not attempt to disrupt, overload, bypass security controls, or misuse the service for unlawful activity. Normal personal use, linking, and search-engine crawling are permitted.
