KK's actual wedding dress is preserved. That being said, we've done numerous wedding-themed encounters. For our first, KK found a dress on e-Bay that she thought was pretty. The encounter was a BDSM role-play theme, featuring KK in that dress as a helpless bride, her ceremony interrupted by a group of men intent on having her, objections aside, reluctance giving in to sub.
She has two wedding dresses in her costume inventory; the first one is now almost rags it's been used so often. KK also has several pieces of wedding lingerie and shoes in her collection, all hot, kinky props for this kind of play.
