Kylie's USP is, of course, her arse, which means you'd probably be doing her from behind most of the time, which addresses any perceived tit-rot/horse-face problems. It won't, of course, help if you'd prefer that she was still in the middle of chemo so you could wip her wig off at the moment of truth, just to add that extra burst of radiant energy (see what I did there?).
