So instead of picking up bikini unlockables, I might as well select the usual tops as such are not water proof and more appealing to the eyes when soaked in body fluids. Other than this feature, costumes will get more dirty as your character gets hit more but no news yet if there's an option for clothing to get ripped. The only thing that I'm afraid to happen is for the female characters to have reduce oppai size for the purpose of "Balance". But I guess that's a good exchange for the sweat engine nevertheless.
Parents should be aware of this feature! and set the options to child friendly settings before your kid gets corrupted of 3D visuals.
