Just the original character design, though the body would be in real detail in the same way a converting computer graphics to photorealistic imagery is. No clipping, nothing like that, just a real flesh and blood body based on the digital image of the character.
Feel free to assume various sliders are a given. If you imagine your character having more junk in the trunk, then it would. The avatar is a representation of the essence of a body, so it's reasonable to say part of the "reality" of the body accounts for mental images of the character as it would be when incarnated.
