Some pasties are for single-use, while others are washable and can be reused. A sideless bikini bottom is sometimes worn to complement a pasties top outfit, this can be a C-string held by an internal flexible frame or other pasties sustained with adhesive, commonly known as a merkin.
Ptosis is the lagging of an eyelid. It has 2 distinct etiologies. Sympathetics going to the eye innervate Muller's muscle, a small muscle that elevates the eyelid. The III cranial nerve also innervates a much larger muscle that elevates the eye lid: the levator palpebrae. Thus, disruption of either will cause ptosis. The ptosis from a III nerve palsy is of greater severity than the ptosis due to a lesion of the sympathetic pathway, due to the size of the muscles innervated.
Sometimes, babies are born with it. You could get ptosis as an adult when the nerves that control your eyelid muscles are damaged. It might follow an injury or disease that weakens the muscles and ligaments that raise your eyelids. Sometimes, it comes with age. The skin and muscles around your eyes get weaker.
