From Forbidden Planet (Fred McLeod Wilcox, 1956): Ann Francis (as Altaira Morbius) models the most expensive dress in movie history, along with its designer Robby the Robot.
Altaira: Robby, I must have a new dress, right away.
Altaira: Oh, but this one must be different! Absolutely nothing must show -- below, above or through.
Altaira: No, just eye-proof will do.
Robby: Thick and heavy?
Altaira: Oh, no, Robby. It must be the loveliest, softest thing you've ever made for me, and fit in all the right places, with lots and lots of star sapphires.
Robby: Star sapphires take a week to crystallize properly. Would diamonds or emeralds do?
Altaira: Well, if they're large enough.
Robby: Five, ten, and fifteen carats, and on hand. I will run the dress up for you in time for breakfast. Sleep well, miss.
Incidentally, that Forbidden Planet remake, written by Babylon 5 auteur J. Michael Straczynski, is apparently still on track over at Warner Brothers. J. Michael is obviously the right guy for the gig, I think, although my heart sank the other day when I learned that it's being produced by Joel Silver, the shlockmeister and vulgarian most recently responsible for the appalling 2009 Sherlock Holmes.
