From 2006.
Leia's Hoth uniform was always one of my favourites of hers - I had actually planned on doing this as far back in my costuming "career" as Halloween 2000, but it didn't happen. I finally got to the point where I was confident in making it - I started on it in December 2005, hoping to have it done for a convention in January, but of course didn't get to it. I quickly realised I didn't have time for it, and only made the jumpsuit - I wore it for the rest of the year at cons as Bespin Escape Leia. In October of that year I finally got to completing all of it :)
The jumpsuit I made earlier in the year - info on it is in my entry for Bespin Escape Leia. For the vest, I used a basic vest pattern - it's three layers, cotton, batting, and the outer material (not sure what it is). I added the piping in the seams, and quilted the lower section. I made the collar and added it. My fiance made my rank badge, as well as the arm communicator piece.
The boots I bought online, and found a grey suede that matched them - I used that to make the wrap parts, and used a darker grey for the straps.
It was all surprisingly easy, and I was very pleased with the outcome. I do want to remake my jumpsuit one of these days, but I'm happy with it for now.
I wore this to Nashville Comic/Horror Festival 2006, Adventurecon 2007 and Dragoncon 2007.
