One of the things I appreciate about Miranda Otto was that she remembered to wear the same combat clothes and chainmail armor as the rest of the Riders of Rohan. Carrie-Anne Moss wore real clothes most of the time throughout the Matrix trilogy except for that weird dress when she arrives at the rave in the 2nd film and the leather get up when she goes inside the matrix; her performance is so well tuned that she actually continues to command our respect despite the leather (which has become a cliche, lets face it).
I forgot to put down Milla 'cause I haven't really seen much of her work. I guess I some rentals to make...
