These are the only three images I got of the jacket--THE JACKET--from the Episode VII exhibit at Star Wars Celebration last spring. When it comes to iconic costume pieces, this will be right up there with the shirts from Brokeback Mountain (omg *ugly-cries just thinking about it*).
Obviously, there are already a bunch of knock-offs available online. Whoever is manufacturing the one with the cheap black plastic buckle clip on the front needs to just stop it. I think I like the one from American Leather Jacket the best: it doesn't have that clip on the front at all and the color is not as nicely distressed/washed out as the original, but it's actually leather and seems to get the weight correct.
Alas Poe, I wish I knew how to quit you.
