I thought this person meant the rumor where if you picked a certain face the breast size was different. I believe it is true, this was important for me and I am female, because I hated being small breasted in XI (come on some us have bigger breasts in real life! even if ladies don't want to admit it, I don't like my pc being boobless)

There was a rumor the uglier elezen female face had the biggest. Its a slight difference guys, but aesthetically it does matter to some people male or female.
