Comic book artists quite often have the same sort of elements pop up in their costume designs. Jim Lee, for instance, is well known for how much he likes to use collars, either high collars or chokers. One of the all-time great costume designers, Dave Cockrum, used so many sashes on his costume designs that he even ended up drawing a cartoon mocking his own overuse of sashes by having a few of his characters pointing out the similarity in their costumes.
Alison Brie looks amazing in Captain America's costume, and if Marvel were to think of developing a female Captain America, she would be perfect for the role. Brie is an actress and producer, popular for her performance in series such as Community and Mad Men, and in films like Scream 4, The Five-Year Engagement, Get Hard, and How to Be Single, among others. It's interesting how she looks as if she is on the set of The Avengers movie.
Pretty much every superhero in comic books has a superpower that isn’t really mentioned. Sure, some billionaire genius could, theoretically, learn how to build powerful metal suit and fight crime similar to Iron Man. However, that person still won’t have all the superpowers of Tony Stark. You see, Tony Stark is a ridiculously attractive man. Wonder Woman, in addition to being a badass warrior that could pretty much dominate any foe, is also incredibly beautiful. Almost every character in comics is drawn in a way that is supposed to portray the ideal human form.
