dearest bel, your personality is a human, (and very humanistic) but i was describing your anatomy! -- clearly, if you met etaoin, (or he/she met you) there would be no question about which pronoun to use! the dress described would fit about a US size 12.. (you're a size 12 i think) but it might be a bit tight on top... still if it were strapless, and shouldless, i expect you'd fit, and fill it out nicely-- and would easily make the garment live up it its name.. man-killer.. any many would kill to go out with you once they saw you in it!

and yes, i suspect it is not really your type dress, but i expect you could play the vamp, even if you don't normally do so!
