#5 Captain America: The First Avenger
Taking a human being and wrapping them up in the American Flag without making them look silly is no easy task. The costume worn in the first Avenger was a fantastic and fresh take on Cap’s costume.

The idea of integrating his costume with the look of a WWII airman’s uniform was a stroke of genius. It makes the costume feel genuine to the time period, yet still retained enough of the classic look from the comic books.

Painted wings on the helm instead of some sort of attached accessory was also a good move. The finishing touch of course is Cap’s Indestructible shield, it looks like an object made of metal and is convincing on screen.
