If prison guard 7 is to wear heels they have to look like weapons. There is to be NO prettiness.. so the prettiness that is 7 can shine through
So yeah chunky heels built up over the whole shoe.
I'm working off Lady Gaga's Telephone video (the uncensored version). 7 is a guard and Russian Janeway is Gaga, a sensualist hardbitten older Gaga. Russian Janeway will of course put Gaga to shame.. you can't project that kind charisma when you're 20 something.
