@purr4me: You can delete just fine in Outfit Studio. You just need to create some weight sliders for the _0 and _1 body weights and than can delete/edit as necessary. Than manually export from Outfit Studio both _0 and _1 nifs and move them to the appropriate folder. @laurellabellabean: If you're moving the vertices, you should be able to move them forward over the nips, not inward into the body. If you're manipulating the clothes, you should be using the inflate tool to inflate the area around the nips. Another solution is rather than manipulate the clothing, you manipulate the body directly and move the nips inward. Depending on how much is covered, you might also be able to just delete the nips from the body layer. Deleting vertices off the body layer is the same as deleting off a clothes layer. It's what I do to minimize clipping by deleting all non-visible skin areas of the body layer. Videos 1 and 2 may be helpful for you.
