I used to watch the repeats of this a long time ago on BBC America, this show ran from 1972 to 1985, I can't imagine a network show here in America getting away with this at that time lol.
Kojima's explanation on how Quiet's nudity and bad boob physics are a essential to the plot:
"Quiet, as her name suggests, is rendered functionally mute after sustaining significant burns to her body while in the field. After undergoing experimental therapy, Quiet is healed and imbued with superhuman abilities…that come with a few caveats. Because her lungs are burned beyond repair, Quiet’s forced to breathe through her skin directly, requiring her to wear little to no clothing, even while in combat. Quiet’s also forced to absorb water directly through her skin in order to stay hydrated."
