From what I've read, Gina was rated either the biggest or second biggest in the industry. She lost a bit of weight and dropped a size since then, though some seem to think she got a reduction. I have no idea where Hyosung's boobs have come from, she never used to be that big; it's either pads or surgery. See here img*360kpo*com/news/2014/08/mqwlmc3*jpg versus here i*imgur*com/VbYwBfA*png
wow i didn’t realize that she lost weight until you said that and i thought about it. she did used to have huge boobs.
your first link doesn’t work but her boobs look good now so who cares about surgery right
