Real covered inverted nipples without obvious areola and make clothes more opaque. I think if the nipple bulge is not suitable in public, then as opposite, the covered inverted nipple, should be rating safe, right?About the 2.0 version：I retrained it with more different pictures to make it more versatile. I'm not sure if it works better, and the trigger words are changed.If the inverted nipples don't appear, then add Prompt：inverted nipples, covered nipples,The Trigger Words is invNp and inv, and inverted nipples is not necessary. If you add it, the nipples will be influenced by the "original" inverting form in your checkpoint and become not smooth.If you don't want the nipple surrounded by areolae to be visible, make it completely sink into the areolae, then add Negative prompt：nipples out,If you want to remove the areolae, then add Negative prompt：pink areolae,puffy areolae,smooth areolae, can help make areolae less obvious
