Soon if he doesn’t start wearing a fucking mask.
It's the one really stupid part of the outfit. Standing in shadows and constantly standing with his back to people is fine every now and then... but half the time there's no way people wouldn't be able to see who he is. It especially becomes an issue now that he's not killing, because during fights there's NO WAY the bad guys can't see his face, and if he leaves them alive... logically, there's nothing keeping them from talking.
It's not quite as bad as Clark Kent's disguise being a pair of glasses... but it's close. On the other hand, I think the domino mask looks really terrible in live-action. Which is why, I assume, they opted to cover half of The Winter Soldier's face in the new Cap movie rather than give him a domino mask.
