Can small or inverted nipples be pierced?
In almost all cases, yes. If your nipple stands out when it is played with or cold, then it can be pierced. If it is very small, you may be limited on how thick the initial piercing will be. But nipples often grow once pierced, so the piercing can usually be stretched after healing. If your nipples are so inverted or flat that they will not come up even when tweaked, your jewelry would most likely grow out, and we do not recommend piercing.
