34G FAQ

What is 34G in EU sizing?
34G (US) is EU 75G. In UK sizing it is 34F. Band conversions are exact; cup fit still varies by brand, style, and body — a conversion is a starting point, not a guarantee.
What are the sister sizes of 34G?
32H and 36DDD — same cup volume, different band.
Is 34G the same in every brand?
No. A 34G can fit differently between brands because of pattern, fabric and cup shape. Use it as a starting point and try a sister size when switching brands.
