I wouldn't be at all surprised to learn that this was once a giant ribbon dispenser attached to the wall of Candy Spelling's reserve wrapping room (used mostly when The Help are busy dusting the other one), and sold on eBay so she could replace it with something larger that might also act as some kind of booby trap against the prying eyes of her children.
We're not strangers to Agatha here at GFY HQ; in fact, we've featured her before as a prime candidate for an "It's A Fug World, After All," ride in which creepy and inanely attired dolls croon hymns of fuggery while you ladel shots from a booze river designed to help you convince yourself it is all a terrible, aggressive hallucination. This outfit might have to appear at a special vodka bar, where you can dock your boat and hold your glass under taps dispensing any number of flavored spirits.
And yet, it might also be considered one of her tamer ensembles.
All hail the heretofore forgotten and hugely batty Good Witch of the South -- who, owing to her blinding lack of restraint and inability to do actual witchcraft, had to make a living in Emerald City as a freelance cobbler and craft-store owner before being chased out of town for upstaging the Horse Of A Different Color and attempting to turn this dress into a scratch-and-sniff game for lonely adult men. Still, she did manage to sell a pair of glittering ruby slippers to that rich, rotten, warty old crone from the East, and we all know how that went, so in a sense the story has a happy -- if slightly bone-crushing -- ending.
