Considering they are making full customization possible you are fully able to do that and make a nasty looking Necro.
I for one am glad that the option for pretty exists. Not all Necros have to be dumpy and disgusting. It’s just as reasonable to have one who looks amazing and has a great deal of confidence and care for herself.
It would be far, far worse if everyone was locked into only making creepy, nasty, disgusting.
