Just a fan-boy aside, the suit IS almost a stright adaption of the one in the comics, just not the iconic one that we're used to seeing. Marvel sort of rebooted the whole universe with a line of books that take place in the "Ultimate" Marvel Universe.they did a damn good job of making the suit look pretty awesome, as opposed to a straight adaptation of the one in the comics, which would have looked ridiculous.
Here's a picture of Cap in WWII from that line of comics:
