i love the ones that are just torsos, especially when they are covered with fabric or are just wire frames. the more life life, the more creepy. and the legs are creepy for real. kinda like these glove molds...http://www.etsy.com/view_listing.php?listing_id=28935734-lauren
also just like the dress busts. That seems like a vintage thing to do, especially if you put like pearls and lacy stuff on it. Not mannequins with heads or arms... that would scare me at night!
