I've always wanted one of these too, for the same reasons Kristen mentions. Thing is - I've tried several on, and the colour just doesn't look that great on me. I look all 'beige' or something. The same thing happens when I try on the classic tan/khaki coloured trench coats.
That said, I'm looking to get out of my black coat rut.
Have you considered taking photos in the store dressing room? I've seen some YLF'ers post pics of things tried on in stores and it works just as well (usually) as buying it, bringing it home, trying to snazz it all up, working up the nerve to post a pic etc. In fact, it might be easier to snap pics of these things in the store.
