The rarest cup sizes are at the extreme ends of the spectrum, such as AAA, AA (especially with small bands like 28AA, 30AA), and very large sizes like G, H, and beyond (e.g., 28G, 30G, 36G), as stores focus on common core sizes (32-38 bands, A-DD cups) and these extremes are harder to find in mainstream retail but available from specialty brands.

This ratio, established by plastic surgeon research, is consistently rated as most attractive by men, women, and surgeons across different demographics, supporting its use as a benchmark in breast augmentation for natural-looking results.
