SimmieV has kilts for men, which look really good. A dark wizard robe and hood. Lots of tattoos too, dragons included. I’ve also downloaded the dragon scale pants.
Necrodog is making a monster factory. Just right for mad scientist Sims. There is a Monster Factory version 2 if you want to try an older version rather than risk the new test version. I also found a wizard if you want to go a bit less science fiction.
