corset piercing
A type of body piercing that consists of multiple piercings in rows, with ribbon, string or chains laced through to mimic the appearance of a corset, though it can be worn anywhere on the body.
Think cross-laced clothes, but it's directly on the skin instead.
In real life, these piercings are only intended to be temporary; they are rarely worn for more than a week. As such, they're typically done for short-term activites, such as a photo-shoot.
They may also be done as a form of piercing play in BDSM.
