Stretch marks are beautiful, normal, and cool. I got 'em, my homies got 'em, lots of people got 'em. So, here we are, finally providing stretch marks, and made for the Bibo+ body. This was a big challenge and I anticipate I'll continue to tweak it into the future. Including in the zip file with the mod is a transparent png, so you can add it to your existing textures.
Stretch marks are added to the hips, thighs, and a lil bit in the back knee, breasts, and under the inner arm.
