A whole heap of us dressed up as Elspeth for Supanova a few years ago, when Isobelle launched The Sending there. I'll try find the photo...because we all picked Elspeth at different times, so there were tons of different outfits...Moonfair Elspeths, gypsy Elspeths, glass statue Elspeth, book cover Elspeths, leaving Obernewtyn Elspeth, INES complex Elspeths, Sadorian Elspeths...
Here you go:
~Link~I was one of the INES-complex Elspeths (I got the most AMAZING long black wig from ebay), but it was a bit of a cop-out costume because it was just jeans, white shirt, black boots. Didn't really work, unless I was with all the other Elspeths (and honestly, nobody but Isobelle really knew who we were dressed up as). Totally agree that you need to have a Maruman :) and the gypsy Elspeth costume always works well (we did that a few years earlier at a small Brisbane-Supanova meet up - can't find the photos any more though, it was so long ago, who knows where they've gone).
