Labrets are one of the most popular styles of body jewelry, as they are primarily used for piercings around the mouth, lips, and cheeks. A Monroe stud, for example, is a piercing placed off center on the upper lip, and is meant to resemble a beauty mark (Marilyn Monroe, the namesake of this piercing, had a very memorable mark in that exact area). iconbodyjewelry.com has the best prices and variety of labrets in steel, titanium, and even hypo-allergenic PTFE options.
