I wore this to a party recently and people loved it.  Although, a lot has to do with how you do your zombie makeup :)  The only thing I didn't like about it was the slippers.  They are more like socks and they do NOT stay on your feet.  I solved this by taking a thin strip of that flesh-colored stretchy sports bandage and wrapping it around my feet to keep them on.  I also used red food dye to make some more blood spatter.
