Edit: bleh; got it working. You pick an outfit, and then STYLES are like color swatches for that outfit. So one outfit can have multiple styles. I picked Elroy, and then the Kingmaker outfit, and it finally gave me a list of the styles for that Kingmaker outfit (I'm using the Tijuana style).

So it DOES work! I've had a few weird little tiny problems with the ps2 version anyway, so I guess it should've been expected (the controller didn't work at first and doesn't seem to want to work in the 1p jack!)
