38G FAQ

What is 38G in EU sizing?
38G (US) is EU 85G. In UK sizing it is 38F. 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 38G?
36H and 40DDD — same cup volume, different band.
Is 38G the same in every brand?
No. A 38G 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.
