Reposting to this thread, as /co/ might have good response:
But more importantly, being totally sexy isn't part of Carol's character--not the way it might be for say, Poison Ivy, who is a seductress in some ways, or Black Cat, who is supposed to be someone who gets the teenage Spiderman's hormones flowing (that's not all she is, of course, and that's arguably not essential either), or Emma Frost, whose control over her sexuality is an important factor of her characterization.
Being strong, and seeming like she has been in fights, is more important to Carol's character. I have full confidence in Brie's ability to handle that.
Also, her suit wasn't fully fitted right now, intentionally. They'll probably give her a suit that fits her better in close-up shots.
