Ah, the miracle of Blu-ray high definition. It really does allow us to see things we couldn't see before. Like the fact that during her much hyped nude debut on True Detective, Alexandra Daddario somehow managed to show her labia, and we're only just now finding this out.
When most actresses do a nude scene, even one in which they show bush, they usually wear a patch over their labia to prevent showing it off, or accidental penetration, but since Woody was a gentleman and kept his pants on, Alexandra probably felt comfortable enough to forgo wearing one. That or she just plum forgot.
Either way, her mistake is our reward as Mr. Skin (link below) has discovered Alexandra's supple lips and their cameo appearance as she climbs off of Woody's woody. But don't take our word for it, see for yourself...
