not exactly dolls per se, but fantasy related so i'll slip it in.
here's where to get the leeloo costume from the 5th elemement in shiny white pvc no less. its their best seller too.
oh and if you don't want to look exactly like the movie then they do it in a range of funky colours too.
wander around the site as they go the extra mile to deliver great sets of images for each of their costumes.
