Jessica looks good on all kinds of hair color. I even like her in black hair, perfect contrast to her luminous fair skin. But if I were to choose between Jess being blonde or brunette, I’d choose blonde. As they say, blondes have more fun! But then they say blondes are bimbos (sorry..) and I don’t want Jess to be associated with that term, so brunette would be the more prudent choice, right? I really don’t know.. But I really love her look when she was a blond bombshell in Sin City. It was classic Marilyn Monroe, much like Christina Aguillera’s look right now. But of course, Jessica is prettier!
