Mermaids have always been a weakness of mine. Due to the "lack" of posability, I've been reluctant to even consider a mermaid BJD. But they are so pretty..! So owners of such leg-less dolls, what are your impressions or thoughts of them, in hindsight (so to say)? Did your doll come with the option of extra legs, or only the tail? What have you found are pros, or cons, about it?
