To be fair, I wasn't seriously expecting The Three Musketeers movies to have nudity (off the top of my head, I can't think of any adaptation of the novel that does), but since Eva was playing Milady, I was a bit optimistic.
Though considering the violence and Milady's seduction scenes, I doubt they were aiming to make the movies family friendly, if that's what you're thinking.
In Liaison, yeah, the intro has Eva having sex (without showing any nudity), but unless I missed something, that just makes it weirder how no episode has a similar scene. Eva appears in a black bra in one episode and that's it.
In Dirty Angels, I think the point of the shower scene was to show Eva's character's tattoos. Make her look badass. Still, it wouldn't have killed them to show some boobs and/or ass as well, lol.
