A bra size that is big on her but not HUGE. She is between 5 feet and 5'1", 98lbs, 22 inch waist, and 34 or 35 inch hips.
By saying "Asian" girl, I mean it's because we're usually really small so I'm using that to also see what bra size would fit. As for those who want numbers, something that's either 32 or 34. Any higher would make look top heavy, right? But thank you for answers you all!
I'm not sure the band size, but I guess a B or a C cup would be nice. But really I don't think breast size is all that important. Being big or small, it doesn't really matter much. Sure guys like breasts, but you might find that guys like breasts of all sizes and shapes, and most of the time we're just happy to see breast, regardless of size.
So yeah, B or C are a nice size, but it's not too important. Bigger or smaller would be acceptable as well.
