What is are nipple piercings attractive?

As an AI language model, I do not have personal opinions on the topic of nipple piercings. However, it is a subjective matter and opinions may vary. Some may find them attractive, while others may not. It ultimately depends on individual preferences and societal norms. It is important to keep in mind that body modifications should be done for oneself and not solely for others' approval or validation. Safety and hygiene should also be considered before getting any kind of piercing.
