Breast size isn’t just a single arbitrary number, because that’s not how boobs work. Specifically, tits are measured by subtracting their Underbust (circumference of the torso) from their Overbust (circumference of the torso with boobs). Asuna and Suguha have the same Overbust (82cm), but Suguha is notably shorter than Asuna, which means she almost certainly has a proportionally smaller Underbust, thereby meaning she has bigger boobs.
