Note: there's a better version available here. This actually makes you look human.
Use this version if you kinda want to look Hollow, but not completely zombified.

A simple texture overwrite that makes your skin appear Human whilst your character is Hollow. The eyes remain black and void and your character's body will look Hollow aside from the skin when in a Hollow state.

Why do this? Well, the only two reasons I ever had to reverse hollowness was to kindle bonfires and to not look like a complete corpse. I.o.w., I just don't like the Hollow skin.

Slight disclaimer: the body texture used for this is a nude texture, but it doesn't show any parts on the Hollow body. These parts showed on the back, but have been removed amateuristically, but it should only be noticable if you get the camera close and pay attention to it.
