Leopard Coat

So leopard coats are my biggest winter lust right now but I am super particular about what I want/ I already have a winter coat/ I'm trying to only buy gifts for people right now.  My obsession started when saw the movie, Factory Girl, and Sienna Miller (portraying Edie Sedgwick) was wearing the most perfect coat.

Amazing, right? And here's the real Edie

Anyways, I've seen a couple on Asos and Nasty Gal but none seem good enough to actually spend the money on.
