Aww. so cute. She's this Lisa Loeb thing going on. That's one very lucky stormtrooper. Also, she's got a long scarf, so she's representin' for the Dr. Who (Tom Baker era) fans as well.
I think she'd leave him for me once she sees my spacetrooper outfit.... that I once read about in the Thrawn Trilogy, and imagined wearing and blowing stuff up in while in outerspace.
And not at all cloying either... really.
Note that your 'hot chick' is also a nerd, dressed as R2-D2.
Now maybe if she were wearing the Leia slave girl outfit...
Benefit to the outfit: hides well the instant boner.
Everybody finds somebody, somehow.
