WANTED: Purple Sable hostess gown

This purple satin hostess gown was worn by Stephanie Beacham on "The Colbys" and to several events, including Nolan Miller's 1988 fashion show.  The outfit is comprised of a belted long purple satin bustier gown that is completely open at the front, revealing matching purple leggings.  I think this outfit is a bit more elegant as a standard gown, but the addition of the open front and leggings of a hostess gown gives it an interesting and dramatic touch.  When Sable moves from scene to scene the gown flutters and flows behind her.

WANTED: If anyone has this gown, or any information on its whereabouts, please let me know!
