Arcanum, for all its general classiness, still has its share of immodesty in art and dialogue.
This mod takes care of most of that. Some changes to replace ladies' underwear and a few armor pieces, plus some alterations to the dialogue in several locations (particularly the brothel, which is now a dental clinic...I wasn't able to fully mod the location, so you may still wish to avoid it, but it has been toned down in case you have to go there to finish a quest or something).Modesty Go!
Note: this mod only works on female outfits. There are five different male body types (as opposed to one female) and each is somewhat time-consuming to modify -- but hopefully I or somebody will see to it, some far-away someday!
