c. Symbolicly, she reminds me of a young, sexy woman who overdresses to impress, yet she's powerful, seductive, and has some hidden secrets. Over time, she becomes more self-confident and covers up...she doesn't need to advertise her sexuality. Indeed, she "ditches" Pike for Kirk. Pike's her first serious boyfriend; Kirk is her husband. She's dressed up for hot night on town with Pike, but later will cover it up and dress down for Kirk, because she's snagged her husband.
By the way, I expect there's a character parallel here in Uhura too. This Uhura is likely a bit mouthy, has an attitude, and can probably school Kirk. She's not going to be taken in by him. She's the woman he can't have; a woman who can, if she wants, have him, and a woman who can tame him. Enterprise is the same way, but she snags Kirk, where Uhura won't have him, and, as we know, Uhura winds up being her "voice," which strikes me as an interesting notion - and like Uhura in TOS, who was sexy and strong, who could wear a mnidress, and yet was a real lady, a "queen," even, so too was the TOS Enterprise we all know and love.
Put another way, in this movie, Uhura is younger and sexier. She's curvier. Heck we see her take off her shirt so we can see her bra. Well, that's the Enteprise in this movie. This is the Enterprise that'll take off her shirt so we can see her bra. Well, TOS Enterprise itself won't take off her shirt, but she's still wearing the sexy miniskirt. There's a evolution here, and I think JJ has picked up on that idea.
