I don't think you will find any nudity here, it's not that kind of game. Now I saw some very sexy and revealing outfits (for archer mostly), maybe some are disturbing to some (?) and if so use options to hide it or ask for such options, or just stay away from the game if is really that bothering. Try out ESO instead maybe, it's extremely hard to find anything sexy in that game, I would play that if it had Astellia's amazing characters and outfits and PvP and even the fighting system (still not sure on this one).
As for female warrior looks, here's this nice concept art from the official page, as you can see no nudity at all and not even revealing at all (later likely there will be more variants to pick from)
