Many skins in SL have a great cleavage but if your favorite skin needs a little more, what can you do? Wear boobs shaders!! I am wearing the Imagen BewbShader3000 on undershirt layer to achieve a subtle "push-up" effect.
My issue with boobs shaders that are not custom made for the skin is that they tend to look more grayish, and not very natural. A lot of my fav skin designers are offering push-up or more cleavage-y versions of their skins now though, so I'm so happy about that <33333!!!!!
Pick up a free copy of the Imagen BewbShader3000 @ Imagen's main store, if you want to try this 😀
