To prevent clipping you can erase portions of the bodysuit, i do almost all of my texture work outside of vroid but for erasing masks and clipping parts i just do it within vroid (on the top right, next to brush color there is a mirror tool which makes this easier).

so the idea is to make each piece of clothing a different bodysuit and texture them individually? are there any masks for the textures so i can work with them in another app?
