Sooo... as the title name of the "mod" says it's just a body preset. To be exact, i tried to recreate the body used in the second and last screenshots of DixiePig's vault jumpsuit mod, with more or less success. But i think it turned out pretty much exactly like the screenshot. 

It took me about 2-4 hours to get the dimensions just right (don't ask why). I've done 3 versions, the first one was...let's say a test that by the end looked like a monstrosity. Version 2 and version 3 are much better. You can use them with other outfits but.... a word of warning... they won't look that great... at least not all of them. But hey, you know go right ahead.  I advise downloading both versions and just choosing the one you like. You can also modify them as you see fit.

If you don't know the mod i'm talking about, here is the link to it
