And, if it's not haute couture, well something straight from the catwalk will have to do.
At last night's 84th Academy Awards, actress Emma Stone was just one of the Hollywood A-list to wear a never worn before dress, in a spring summer 12 Giambattista Valli couture creation, seen on the couture catwalk just a month ago.
The Artist actress Berenice Bejo, opted for Elie Saab spring summer 12 couture, also wearing a dress that was also shown during Paris couture week just weeks ago.
Gwyneth Paltrow wore a dress from Tom Ford's closely guarded autumn winter 12 collection; only seen by a handful of people to date (and so closely guarded there are no other images of it). Also in white was The Descendants actress Shailene Woodley, who also opted for couture in a Valentino spring summer 12 couture gown.
Exclusivity is a must when it comes to the Academy Awards, and wearing the same dress that someone has seen, let alone worn before, is the ultimate Oscars offence.
If its exclusive youre looking for, then plundering the archives of the worlds most covetable couturier to source your dress doesnt get much better. Cue < More
