You do that
but anyways I think that the easiest way to avoid such nasty run ins with ridicoulus pamela-anderson sizeds on matoran sized mocs and the crazed " This is just sick, it's innapropriate for our younger members, I SUE YOUZ BZPERS! LOLZ" members who think they're members of the media ratings association or whatever that group is called who are actually making it a problem when the femal moc wasn't a problem in the first place. The easiest way to avoid this, not to mention avoid having a ridiculous looking moc is to make a pair of, uh, female chest parts from scratch that are well poportioned to the female moc size. It's that simple.
