I saw a post about the scene and realized how could V strip while still connected? I assumed they didn't disconnect from the vehicle, which means they either did one of these two options.
Poking the shirt through the cable is the most reasonable but is awkward and wasn't in the cutscene.
Stretching your shirt over your body is also possible but doesn't make sense for some shirts+ combat gear. I realize Panam's fit isn't much of a problem. Jackets and stretchy/buttoned shirts also pass but it's still a little awkward
Needless to say my immersion is ruined, 0/10 game
