It's not really boobs under there. It's just clothing. Same as with my lamia litch model. And believe it or not there is a logical reason for this. Lithches are not mindless undead. And as far as I am concerned that means that just because they are undead does not mean they are going to abandon the niceties of life. Sure they can't enjoy food or drink or sex any more, but they are still human. So things such as fine clothes or jewelry are still going to be a thing they wear. They are still going to want nice furniture, cool staffs, etc. Especially in case of those individuals such as archmages (the sort of people that become a litch) where those things are part of the uniform. So I feel that even in undeath a female is likely to have some sort of reminder of her femininity in there. Just like a male undead knight is still likely to keep the codpiece on his plate armor. Plus there is something just flat out cool about a sexy skeleton.
